apport-retrace 1.21.2-0ubuntu4 (i386 binary) in ubuntu oneiric

 apport-retrace recombines an Apport crash report (either a file or a
 Launchpad bug) and debug symbol packages (.ddebs) into fully symbolic
 stack traces.
 .
 This package also ships apport-chroot. This tool can create and
 manage chroots for usage with apport-retrace. If the fakeroot and
 fakechroot libraries are available (either by installing the packages
 or by merely putting their libraries somewhere and setting two
 environment variables), the entire process of retracing crashes in
 chroots can happen with normal user privileges.
