Application that crashed: systemsettings
Version of the application: 1.0
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.6.2
Operating System: Linux 2.6.34-rc1 x86_64
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
It crashs when I tried to enter into desctop settings and switch effects from
openGL to Xrander. I don't use gallium and that is strange for me why it is in trace.

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