Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-13-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

Was using firefox, not interacting with the desktop, taskbar, or any widgets at all. No widgets on desktop, Taskbar is mostly identical to the default version in Kubuntu 11.04, except on the top of the screen instead of the bottom.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
