Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-trunk-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
KDE-Plasma crashes with segmentation fault 11. All I had done was made an upgrade via aptitude safe-upgrade. Every other desktop environment seems to function fine (LXDE, Fluxbox). I can use all kde applications, exept that I must do it via Alt+F2.

 -- Backtrace:
