Description Teunis 2011-12-13 14:36:36 UTC
Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

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

I right-clicked a picture in Firefox to save it.When the download window momentarily appeared Plasma crashed. There is not always a crash but say 1 in 20 times.
Strange is that many windows/programs initially open full screen, this includes said download window.
The problem has started the first week of December.

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