Bug 275523

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.3 (4.6.3) "release 4"
Qt Version: 4.7.3
Operating System: Linux 2.6.37.6-0.5-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Actually the crash came out of nowhere. I suspect it has to do with quite heavy disk io (video processing and extracting a track from a video at the same time) and the that I'm usign a wacom tablet where you often accedentaly start drag & drop operations.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault
