Application: systemsettings (1.0)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-3-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

-- Information about the crash:
In System Settings, I click on the Multimedia button but the window does not open at all. Eventually, system settings crashes.
Looks like a phonon bug as I have not been able to get sound on my 4.4.1 installation. (Previous version 4.3.4 did have sound)

The crash can be reproduced every time.

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