Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
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:
As title. Only other thing to note is that I have two panels on my desktop rather than one.

The stack trace looks similar to the other bug, but since the line numbers are different I figure better to be safe than sorry.
