Bug 217877

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-rc8-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
I can't think of anything suspicious that I was doing which could have led to plasma crashing. Hoping perhaps the backtrace can say more.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
