Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30kala i686
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
KDE starts, plasma-desktop starts to run but crashes, manual restarting doesn't help - still crashes.

 -- Backtrace:
Application: Plasma töötsoon (plasma-desktop), signal: Segmentation fault
