Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.3 (KDE 4.5.3) "release 8"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.5-default i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
I upgraded to KDE 4.5.3    btw: it was not the best idea

Now the Control bar crashes once in a while.
- No K-Menu
- No systray
- no prog-switch
- no other widgets......

ALT-F2 works.

The other annoyence:
- the windows just have no "minimize" "maximize" "close" buttons

The crash can be reproduced every time.

-- Backtrace:
