[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Kenneth Wrede (kennethwrede)]

Xubuntu 64bit, updated Saucy 13.10. Custom kernel 3.4.0

[Milan Bouchet-Valat (nalimilan)]

Upstream (I) no longer maintains the g-s-t for several years, and the git repository has even been archived. XUbuntu needs to find another user management tool based on accountsservice.

BTW, this bug lacks a proper backtrace to be of any use.

[Alberto Salvia Novella (es20490446e)]

Thanks Milan for this information.

David, please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

[Elfy (elfy)]

I've seen the same bug.

Hope the attached actually is the backtrace you want

[Alberto Salvia Novella (es20490446e)]

Since the uploaded crash contained a CoreDump, which will potentially have sensible information, I have created a new version with the dump been removed.

Elfy; please remove the crash you have uploaded, so I can mark this bug as public again.

[Alberto Salvia Novella (es20490446e)]

Oh, Elfy, I just realized I could delete your attachment myself; so there's no need you to do so.

[David Pires (slickymaster)]

It's a good thing Elfy managed to upload his backtrace since it would be impossible for me to do it because the crash happened in my tests machine, which since then has been several times formatted to continue testing .

[David Pires (slickymaster)]

I'm uploading the backtrace of the same crash on today's daily build (2013-10-14), since it's reproduced in the same hardware and performing the sames steps as described in the original report.

[Alberto Salvia Novella (es20490446e)]

Since the uploaded crash from David also contained a CoreDump, which will potentially have sensible information, I have created a new version with the dump been removed.

[Thaddaeus Tintenfisch (thad-fisch-deactivatedaccount)]

Please add the PPA https://launchpad.net/~thad-fisch/+archive/test and test the patched gnome-system-tools package (trusty).

[David Pires (slickymaster)]

Added thad-fisch's PPA and re-run the add user test without any problems. Therefore I can confirm that the proposed patch works.

[Launchpad Janitor (janitor)]

This bug was fixed in the package gnome-system-tools - 3.0.0-3ubuntu4

---------------
gnome-system-tools (3.0.0-3ubuntu4) trusty; urgency=medium

  * Add 12_fix_exit.patch: Drop unneeded g_object_unref call to fix a
    segmentation fault on exit after a new user has been created. Adjust
    gst_users_tool_finalize to fix some warnings/error messages. Thanks
