Bug 323780

Application: systemsettings (4.11.00)
KDE Platform Version: 4.11.00
Qt Version: 4.8.4
Operating System: Linux 3.8.0-27-generic x86_64
Distribution: Linux Mint 15 Olivia

-- Information about the crash:
- What I was doing when the application crashed:
I installed the 4.11 backports files. All this happened upon login after the splash screen
- Unusual behavior I noticed:
Blank screen with only a mouse pointer and System Settings menu When I tried changing desktop appearance, the program crashed. Similar-sounding bugs suggested were all Amarok bugs.
- Custom settings of the application:
None that I know of; this is a new KDE application on a Linux Mint 15 MATE system. If asked, I can gztar up my ~/.kde folder (I presume that's where settings are saved, and I have had a .kde folder in /home for a long time.

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