Mistakenly set it as affecting me, but it doesn't. The test case returns '1' for me. So I'm setting it back to 'New'.

Hi Daniel,
I can't get this to trigger on my 12.04 system, could you include a copy of your /etc/apt/apt.conf.d and /etc/apt/preferences.d?
Another suggestion you could try would be to install the ddebs and then run apt-cache search under gdb and ctrl-c it somewhere in the middle, hope you hit the slow patch and then try and get a backtrace to see how it got there.

When running it in gdb, I get the following backtrace:
Starting program: /usr/bin/apt-cache search apt
^C
Program received signal SIGINT, Interrupt.

So it looks like the iterator used to get translated descriptions causes this.

This gets triggered by the following configuration:
% cat /etc/apt/apt.conf.d/20notranslation
Acquire::Languages "none";

summary:

"apt-cache search" is slow because of listing /var/lib/apt/lists 45227
- times
+ times (triggered by 'Acquire::Languages "none";')

    - add spaces around PACKAGE_VERSION to fix FTBFS with -std=c++11

    - make IsDuplicatedDescription static so that it is really private
      as we don't need a symbol for it as it is not in a header
  * Makefile, buildlib/*.mak:

    - separate manpages from the rest of the doc building
  * prepare-release:
    - apt-inst version isn't apt versions, so don't override variable

    - apt-utils packages manpages, so it should depend on build-doc
    - make apt and apt-utils packages depend on manpages instead of full doc

      of [architecture restrictions] in Build-Depends (Closes: #672927)

      as untranslated for po4a removing ~200 unless "translateable" strings

    - longcode Translation files are saved with encoded underscore,
      so make sure to pick these files up as well for Acquire::Languages

    - include Contents-* files in Release files (Closes: #673647)

  * apt-pkg/contrib/configuration.cc:

    - normalize a bit by replacing // and /./ with / in FindFile

    - implement --empty and --format option for dump

    - use Dump() to generate the configuration output
  * apt-pkg/depcache.cc:
    - clearly separate 'positive' and 'negative' dependencies and
      their upgrade-resolution tries in MarkInstall and especially don't
      treat Conflicts differently compared to Breaks here
    - provider is only a possible solution if the provides has the right
      version (or none as we have no versioned provides in debian) and not
      if the version of the provider matches
  * edsp/edspsystem.cc:
    - check with RealFileExists for scenario file as otherwise a directory
      like one provided with RootDir triggers the usage of EDSP
  * debian/libapt-inst1.5.symbols:
    - use the correct library name the symbols header
  * apt-pkg/pkgcachegen.cc:
    - check if NewDescription allocation has failed and error out accordingly

      we end up working on dangling pointers otherwise which segfaults on
      s390x and ppc64 (Closes: #669427)

    - check length and containing chars for a given description md5sum
  * ensure that apti18n.h is included last as advertised (Closes: #671623)
  * apt-pkg/acquire-worker.cc:
    - revert the use of FileFd::Write in OutFdReady as we don't want error
      reports about EAGAIN here as we retry later. Thanks to YOSHINO Yoshihito
      for the report. (Closes: #671721)
  * apt-pkg/contrib/fileutl.cc:
    - check that the fd which are closed are valid
    - ensure that we do init d only once and especially not with its own
      content as this causes some "interesting" hickups resulting in segfaults
      as it seems (Closes: #554387, #670979)
    - collect zombie (de)compressor processes on reopen
    - ensure that in error conditions the Fail flag is set
    - ensure that d is set before accessing it

  * apt-pkg/contrib/sha2_internal.cc:
    - do not use the input data directly but memcpy it instead as
      it could be unaligned as in the http-transport which causes
      a sigbus error on sparc (Closes: #669061)

    - fix inconsistent clog/cout usage in the debug output

      ordering code does not get into a endless loop when it flip-flops
      between two states
  * update libapt-inst1.4 to libapt-inst1.5 because of the cleanup
    performed
  * prepare debian/unstable upload, if there are no issues with this
    upload it will directly go into unstable as 0.9.0

[ David Kalnischkies ]
  * do not update po and pot files in the process of the build as this
    causes timestamp changes for the mo files which therefore can't
    be refcounted by dpkg for your M-A: same packages
    (Closes: #659333, LP: #924628)
  * apt-inst/database.{cc,h}, apt-inst/deb/dpkgdb.{cc,h}:

      and comes straight from the beginning of last decade (Closes: #663372)
  * apt-inst/deb/debfile.cc:
    - {Extract,Merge}Control() is another instance of "lets reimplement dpkg"
      so shot of this code before someone ends up using this…
  * debian/libapt-pkg4.12:
    - update symbols file
  * debian/apt-utils.install:
    - ship the ftparchive, apt-extractemplates and apt-sortpkgs locales
      in the apt-utils package instead of the apt package
  * apt-pkg/packagemanager.cc:
    - recheck all dependencies if we changed a package in SmartConfigure
      as this could break an earlier dependency (LP: #940396)

    - add libbz2-dev as new build-dependency
    - remove the libz-dev alternative from zlib1g-dev build-dependency
    - suggest xz-utils instead of bzip2 and lzma
  * doc/apt-get.8.xml:
    - typofix: respect → respecting, thanks Mike Erickson! (Closes: #664833)
  * debian/rules:
    - do not sed in configure.in to set the version-number
  * prepare-release:
    - add as a small script to lazy check and prepare releases
  * doc/*:
    - move the command synopsis out of each manpage into apt-verbatim.ent
      as they are a hell to translate and just single out the parameters
      which can be translated to apt.ent
  * apt-pkg/aptconfiguration.cc:
    - if present, prefer xz binary over lzma
    - if we have zlib builtin insert add a dummy gzip compressor for FileFD
    - do the same for bz2 builtin if available
  * methods/bzip2.cc:
    - remove it as the functionality for all compressors can be
      provided by gzip.cc now with the usage of FileFD
  * apt-pkg/contrib/fileutl.cc:
    - use libz2 library for (de)compression instead of the bzip2 binary as
      the first is a dependency of dpkg and the later just priority:optional
      so we gain 'easier' access to bz2-compressed Translation files this way
  * cmdline/apt-get.cc:
    - print list of autoremoves in alphabetical order (Closes: #639008)

[ Bogdan Purcareata ]
  * doc/apt-get.8.xml:
    - add 'download' to the usage line (Closes: #649340)
  * cmdline/apt-get.cc:
    - distinguish information about 'apt-get autoremove' based on the
      number of auto-removed packages both before and after the list
      of packages (Closes: #665833)

[ Steve Langasek ]
  * don't treat build-depends-indep as cross-build-dependencies; we should
    always install the host arch versions.  LP: #968828.

[ Paolo Rotolo ]
  * Fix string from automatic to automatically (LP: #967393).

apt (0.8.16~exp13) experimental; urgency=low

[ David Kalnischkies ]
  * apt-pkg/acquire-item.cc:
    - remove 'old' InRelease file if we can't get a new one before
      proceeding with Release.gpg to avoid the false impression of a still
      trusted repository by a (still present) old InRelease file.
      Thanks to Simon Ruderich for reporting this issue! (CVE-2012-0214)
    - add Debug::pkgAcqArchive::NoQueue to disable package downloading
  * apt-pkg/deb/dpkgpm.cc:
    - chroot if needed before dpkg --assert-multi-arch
    - ensure that dpkg binary doesn't have the chroot-directory prefixed
    - call dpkg --assert-multi-arch with execvp instead of execv
    - save the universe by not printing messages about apport if a package
      with this name is not installed (Closes: #619646)
    - handle a SIGINT in all modes as a break after the currently running
      dpkg transaction instead of ignoring it completely
  * apt-pkg/depcache.cc:
    - if a M-A:same package is marked for reinstall, mark all it's installed
      silbings for reinstallation as well (LP: #859188)
  * apt-pkg/contrib/configuration.cc:
    - do not stop parent transversal in FindDir if the value is empty
  * methods/http{s,}.cc:
    - if a file without an extension is requested send an 'Accept: text/*'
      header to avoid that the server chooses unsupported compressed files
      in a content-negotation attempt (Closes: #657560)
    - remove the arbitrary MAXLEN limit for response lines (Closes: #658346)
  * apt-pkg/aptconfiguration.cc:
    - chroot if needed before calling dpkg --print-foreign-architectures
    - ensure that architectures are not added multiple times
  * cmdline/apt-mark.cc:
    - detect if dpkg has multiarch support before calling --set-selections
    - correctly ignore already (un)hold packages
  * apt-pkg/cachefile.cc:
    - clean up lost atomic cachefiles with 'clean' (Closes: #650513)
  * apt-pkg/indexrecords.cc:
    - do not create empty Entries as a sideeffect of Lookup()
  * apt-pkg/acquire-item.cc:
    - drop support for i18n/Index file (introduced in 0.8.11) and use
      the Release file instead to get the Translations (Closes: #649314)
    - use pdiff for Translation-* files if available (Closes: #657902)
  * ftparchive/writer.cc:
    - add 'Translation-*' to the default patterns
  * cmdline/apt-get.cc:
    - if a package can't be removed as it is not installed, suggest to
      the user an (installed) multiarch silbing with 'Did you mean?'
    - improve 'error' message for packages which are only referenced
      e.g. in a Depends line and are now requested for removal
  * cmdline/apt-cache.cc:
    - correct --pre-depends option by using dash consistently (LP: #940837)
  * apt-pkg/packagemanager.cc:
    - do not try to a void a breaks if the broken package pre-depends
      on the breaker, but let dpkg auto-deconfigure it
  * apt-pkg/contrib/fileutl.cc:
    - do not warn about the ignoring of directories (Closes: #662762)

[ Steve Langasek ]
  * cmdline/apt-get.cc:
    - for cross-build-dependencies M-A: none should be DEB_HOST_ARCH,
      not DEB_BUILD_ARCH (Closes: #646288)

[ Colin Watson ]
  * apt-pkg/algorithms.cc:
    - don't break out of the main-resolver loop for Breaks to deal with all
      of them in a single iteration (Closes: #657695, LP: #922485)
    - use a signed int instead of short for score calculation as upgrades
      become so big now that it can overflow (Closes: #657732, LP: #917173)
  * Fix IndexCopy::CopyPackages and TranslationsCopy::CopyTranslations to
    handle compressed files again (LP: #924182, closes: #658096)

[ Michael Vogt ]
  * apt-pkg/deb/dpkgpm.cc:
    - fix crash when a package is in removed but residual config state
      (LP: #923807)
  * apt-pkg/contrib/fileutl.h:
    - fix compat with FileFd::OpenDescriptor() in ReadOnlyGzip mode
  * apt-pkg/packagemanager.cc:
    - fix bug in predepends handling - ensure that packages that needs
      unpackaging are unpacked before they are configured (LP: #927993)

[ Julian Andres Klode ]
  * apt-pkg/deb/deblistparser.cc:
    - Set the Essential flag on APT instead of only Important
  * apt-pkg/packagemanager.cc:
    - Do not use immediate configuration for packages with the Important flag
  * Treat the Important flag like the Essential flag with those differences:
    - No Immediate configuration (see above)
    - Not automatically installed during dist-upgrade
    - No higher score for installation ordering
