Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1))
Qt Version: 4.5.0
Operating System: Linux 2.6.29-02062901-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Plasma crashed, but before it did, alot of the plasmoids started "leaking" graphics from other plasmoids into different plasmoids. Graphical glitches appeared for awhile, then it crashed. Things went back to normal when plasma returned.

 -- Backtrace:
