/usr/bin/gnome-control-center --version
gnome-control-center 3.1.91

this is followup from my above crash report,
now it repeatedly core dumps when I launch :

/usr/bin/gnome-control-center

then after its window opens I use mouse and click on icon : User Accounts

Segmentation fault (core dumped)

please advise on any debugging you would recommend

Thank you for your bug report. Pedro can you upstream it? You can add that l1168 is " if (is_unique_language (language_code)) {"

[Pedro Villavicencio (pedro)]

Thank you for your bug report. This bug has been reported to the developers of the software. You can track it and make comments at:

[VladimirCZ (vlabla)]

I just want to add here that the User Accounts setting does not work at all and causes the crash both in Unity and in Gnome Shell. Ford details, please, see to the Bug 863032.

[Jakob Malm (malmjakob)]

I experience this problem on 64 bit Ubuntu 11.10 beta2.

[Damian Beltrami (damian-beltrami-id)]

Clean install of Ubuntu 11.10 has removed this problem for me

[Launchpad Janitor (janitor)]

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

[Martin Pitt (pitti)]

Hello Scott, or anyone else affected,

Accepted gnome-control-center into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Michael DePaulo (mikedep333)]

Martin Pitt, That worked!
Updating gnome-control-center & libgnome-control-center from oneiric's 1:3.2.0-0ubuntu6 to oneiric-proposed's 1:3.2.1-0ubuntu1 fixed this bug for me.
(Done on AMD64)

Segmentation fault
(after clicking on User Accounts)

[Jander Moreira (moreira-jander)]

This problem doesn't happen when using Unity.

[Jander Moreira (moreira-jander)]

I've found this bug page when looking for the solution to another problem.
Gnome-shell was crashing with the gnome-shell-extensions-alternative-status-menu. The workaround I found was just to set the picture in the user profile.
Then I've found User Accounts was crashing, what I wasn't aware of.
In Unity, I put a picture in my profile. After rebooting, everything works fine: both User Accounts and the shell extension.

I'm really not sure if there is an actual relation between these issues, but was a workaround for me.
