KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Just resumed after a suspend to RAM. The crash seems totally random and don't see an obvious culprit in the backtrace.

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