The stack trace for this bug report has the bug reporter's email addresses in them so perhaps should not be made public.

@Chris it would be helpful if we could make this bug report public. You can do this yourself by clicking the pencil next to 'This bug report is Private'. Thanks!

I'm having a look, but my software-center/python/glib foo is not huge so if anyone has a hint of where the bug may be i'll be happy to listen to it :-)

Found a fix/workaround, seems that some variables were going "out of scope" and being freed too early, not sure if that might be a pygobject bug or the previous usage was wrong. Anyone with more knowledge in the area?

This is 100% reproducable in trunk, e.g. via:

$ PYTHONPATH=. gdb --args python ./utils/submit_review_gtk3.py --pkgname enigmail --iconname enigmail --version 2:1.4.4-0ubuntu1 --origin ubuntu --datadir ./data --debug

This appears to be crashing for any review.

  [ Michael Vogt ]
  * lp:~mvo/software-center/lp1044141:
    - fix unicode error crash on a transaction error
      (LP: #1044141)
  * lp:~mvo/software-center/fix-size-calc-race:
    - fix crash due to a race in the size calculation code
      in the details view (LP: #1041004)
  * lp:~mvo/software-center/fix-crash-1048886:
    - No longer call GLib.init_threads() as this will cause
      LP: #1048886 later. Many thanks to Albert Astals Cid
  * lp:~mvo/software-center/dbus-idle-timeout:
    - stop the dbus data provider after 5min of inactivity
      (LP: #1058567)
  * lp:~mvo/software-center/lp1051829:
    - Do not report deb packages with lintian errors via the
      recoverable errors mechanism. This removes 97 out of 104
      instances of my sample of the recoverable error report
      for LP: #1051829. Other types of failures will still be
      reported as recoverable failures though (as we do want
      to know about them).

  [ Gary Lakser ]
  * lp:~gary-lasker/software-center/lp1041004:
    - ensure that app_details is valid before using it (LP: #1041004)
  * lp:~gary-lasker/software-center/fix-crash-lp1021308:
    - send synthetic "style-updated" signals to ensure that the signal
      handlers are called on themes that do not send this signal (like
      oxygen-gtk3). This fixes a crash and broken drawing LP: #1021308

  [ Nicolas Delvaux ]
  * lp:~malizor/software-center/fix-lp1050036:
    - fix crash in get_label() (LP: #1050036) and drop the i18n for the
      yes/no symbols that were not translated in any language (as a result
      test_regression_lp1047281.py can also be dropped)
