Bug Description

Here is how to reproduce this bug:
 * Download http://fgouget.free.fr/bugs/testdep.tar.bz2
   This is a small archive that contains a set of test, empty, Debian package files along with their source.
   (run ./build to rebuild them)

 * Install the testdep-same_1.0-1_amd64.deb package.

 * Then run: qapt-deb-installer testdep-same-arch_1.0-1_i386.deb

qapt-deb-installer will then refuse to install the package with the following error:

    Status: Error: Cannot satisfy dependencies

Yet testdep-same-arch has 'testdep-same:amd64' as its sole dependency so the installed amd64 testdep-same package should satisfy it. Running dpkg confirms this:

$ sudo dpkg -i testdep-same-arch_1.0-1_i386.deb
Selecting previously unselected package testdep-same-arch.
(Reading database ... 214863 files and directories currently installed.)
Unpacking testdep-same-arch (from testdep-same-arch_1.0-1_i386.deb) ...
Setting up testdep-same-arch (1.0-1) ...

Finally, note that support for this type of dependency qualifier has been added in dpkg 1.16.5. For more details see:

* Bug #676232: dpkg: Please add support for specific arch qualifiers (cross-dependencies)

  Add support for specific arch-qualified dependencies

  This allows to use dependencies with arch-qualified package names. For
  example:

    Depends: libc6:amd64 (>= 2.14), libgcc1

  Closes: #676232

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. While we appreciate your issue, it would be better if it was tracked at https://bugs.kde.org, so that the KDE developers can deal with this speedily and have direct communication with you as the reporter for more effective debugging.

Thanks!
