Package: aptitude
Version: 0.8.3-1

Hi Manuel,

after an aptitude "Performing actions" run I typed "q" and pressed

While the "Updating … and quitting" screen was shown I already started
to type "update-alternatives --config" and aptitude segfaulted with the
following backtraces:

warning: core file may not match specified executable file.
