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: 4.5.1
Operating System: Linux 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I had several windows open; kate, dolphin, synaptic, firefox, wine-doors, Ark, I had just extracted an archived file, and I was also doing an up with synaptic, so I'm not sure what app. caused the crash.
Sorry if this isn't too helpful.
