Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic-pae i686
Distribution: Ubuntu 11.10

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

I opened a new activity (I only had one running), so now I had two activities. I went to the 2nd one and closed the 1st one. The crash happened while closing the activity which I was using at first.

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