Application: systemsettings (1.0)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.9-70.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
I compiled the VLC phonon backend from source and installed it on my up-to-date Fedora 12 64bit system (KDE 4.4.1). Whenever I now try to start the system settings dialog to configure the phonon backend or e.g. try to play a video with the dragon player I get a crash in module_list_get.

The crash can be reproduced every time.

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