Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.7.1 x86_64
Distribution: Ubuntu 12.10

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

I have configured two activities in KDE. When I switched to second and stop first, desktop stops responding and a few seconds later Plasma crash.

I tried these operations again but crash was not repeated.

The crash does not seem to be reproducible.

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