Bug 290336

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
This time I opened a lot of pics in GIMP. I have had problems with pic and video editing programs for some time now. Mostly crashing plasma desktop. I can still work though, but the programs not always do what I tell them ro or does something completely random. This time GIMP blacked my pic and added a supernova-like field too, I suppose GIMP or/and the crashed plasma didn't like my pic or the fact that I was switvhing programs using ALT + TAB.

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