Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
I had 5-6 instances of QtCreator opened with some projects. The windows were grouped in to the title bar. I wanted to close them all so I right clicked on the item and selected close, for the moment nothing happened and I right clicked again, the menu poped up and just a second before I clicked close again the application dissapeared but I was already clicking close and this caused a crash.

The crash can be reproduced some of the time.

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