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

What I was doing when the application crashed:
I'd just activated "Present Windows", and clicked on the desired window (Firefox 3.0.10) when plasma crashed.

I'm on Kubuntu Jaunty AMD64 using FGLRX 9.4 running KDE 4.3 beta 2 (and *loving* it :).
I'm using an AMD Phenom II quad core cpu and 4gig of ram. There was very little open at the time other than a couple of kate instances and a FF window with only a couple of tabs open and 2 dolphin instances using sftp KIO's.
