Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1) "release 169"
Qt Version: 4.5.2
Operating System: Linux 2.6.27.29-0.1-default i686

What I was doing when the application crashed:
I added the 'show desktop' plasmoid to an auto-hiding panel on top of my screen. When clicking on the plasmoid, plasma-desktop crashed. It works fine if I click it now.
