Bug 275143

Application: systemsettings (1.0)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.39-mabs x86_64
Distribution (Platform): Exherbo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I wanted to change the phonon engine from vlc to gstreamer, 
the moment I clicked save systemsettings crashed with the attached backtrace.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Systemindstillinger (systemsettings), signal: Segmentation fault
