Application: plasma-desktop (0.3)
KDE Version: 4.3.71 (KDE 4.3.71 (KDE 4.4 >= 20091007)) (Compiled from sources)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I changed many settings yesterday, and now its crashing on startup.
A white rectangle comes in upper-left corner and then it crashes.
