Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1)) "release 209"
Qt Version: 4.6.0
Operating System: Linux 2.6.31.8-0.1-desktop i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
I just closed a window (I think it was a gvim one), where plasma crashed.

It might be interesting to mention that since I upgraded to 4.4 RC1 I have these crashes every few minutes, while I had NONE with 4.4 beta 2.

The crash can be reproduced some of the time.

 -- Backtrace:
