Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.2 (KDE 4.4.2) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
I was recently updating my arch64 and in middle of the process KDE crashed. I restarted computer and graphic was scrambled (desktop didn't load up) I tried removing xorg.conf and graphic started and crashed after few s. I restored the old xorg.conf and same thing happened. But I am still able to use applications and start them thru alt f2 but i-m browsing on internet for some days and can't seem to find a solution.

The crash can be reproduced every time.

 -- Backtrace:
