Application: systemsettings (1.0)
KDE Platform Version: 4.10.00
Qt Version: 4.8.2
Operating System: Linux 3.2.0-31-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:

i was trying to select the theme for the login screen (because the background is now just solid black color and this is ugly).

- Unusual behavior I noticed:

Somehow all my tray icons got messed (for instance, Skype icon moved to the top of the screen (some_x; 0) and did not respond to clicks). Restarting the PC did not help. But seems that updating the packages fixed that.

On the other hand, system notifications are now at the top-left corner of the screen and i can't get them out of there.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
