KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.34.7-0.3-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:If VLC is chosen as backend for phonon then clicking on "System Settings>Multimedia>Phonon" causes "System Settings" to crash.

The crash can be reproduced every time.

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