Application: plasma-desktop (0.3)
KDE Version: 4.3.74 (KDE 4.3.74 (KDE 4.4 >= 20091102)) (Compiled from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.32-rc6-custom x86_64

What I was doing when the application crashed:
When I clicked the power plasmoid in systray and tried to drag the extender off panel, plasma-desktop crashed.
