Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I don't know the exact steps of reproduction, it was just normal usage. I am using quite a few plasmoids, lancelot instead of the standard k-menu, and kwin compositing (on a radeon HD4870 using fglrx 9.4).
