Fixed in trunk r2184.

This bug was fixed in the package apport - 1.94-0ubuntu1

---------------
apport (1.94-0ubuntu1) precise; urgency=low

  [ Martin Pitt ]
  * New upstream release:
    - apport: Set the group of written reports to "whoopsie" if that group
      exists.
    - Fix tests to run properly against the system-installed modules and
      binaries.
    - test/run: Run under LC_MESSAGES=C to avoid test failures due to
      translated strings.
    - general-hooks/generic.py: Also attach xsession-errors for programs that
      link to libgtk-3.
    - launchpad.py: Properly handle "Expired" status, to avoid marking new
      bugs as duplicates of expired ones. (LP: #941854)
    - apport: Fix crash if the "whoopsie" group does not exist. (LP: #942326)
    - report.py, crash_signature(): Do not put "<module>" frames into Python
      crash signatures that happen outside of function/method calls. Fall back
      to the file/line number as a frame description instead. This will do a
      much better job at disambiguating e. g. different ImportError crashes.
      (LP: #920403)
    - Make "binary changed since the time of the crash" error message more
      comprehensible, thanks Paolo Rotolo. (LP: #942830)
    - crashdb.py, check_duplicate(): It can happen that a bug gets identified
      as being a duplicate of bug S by symbolic signatures and a duplicate of
      bug A by address signatures. Empirical evidence shows that this is due
      to the unavoidable jitter in stack traces (A and S not being identified
      as duplicates as their signatures differ slightly) and not a logic
      error. So instead of erroring out, duplicate all three bugs and keep the
      lowest number as the master ID. (LP: #943117)
    - Revert the usage of multiple nested threads during data collection, and
      switch back to only using one UI thread. The UI implementations can, and
      now do, decide between showing a spinner and showing a progress dialog
      in the ui_*_info_collection_progress() methods. This fixes libX11
      crashes when multiple UI threads do changes concurrently (LP: #901675),
      and also avoids multi-thread induced crashes in Pango (LP: #943661). The
      removal of the collect() method also fixes the new crashes in it.
      (LP: #942098, #939803)
    - ui.py, get_desktop_entry(): Fix crash on uninstalled package.
      (LP: #940984)
    - data/unkillable_shutdown: Fix crash on race condition when PID goes away
      while the report is created. (LP: #546369)
    - apport/hookutils.py, pci_devices(): Fix crash on unexpected lines from
      lspci. (LP: #904489)
    - Drop hardcoded "Ubuntu" words again which crept in with the whoopsie
      support merge. Use the DistroRelease: field.
    - apport-kde: Fix Home page URL in KApplication metadata.
    - apport-gtk: Fix resizability and size after hiding details.
      (LP: #405418)
    - test/run: Drop "local" argument. This now tests against the source tree
      when run in the source tree root, and against the system
      libraries/programs when run from anywhere else.
    - test/run: Consider command line arguments as test names and only run
      those when given. Also support just runni...
