Bug 237444

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-0.2-desktop i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
After installing a patch (incl. plasma), I always get a segfault while starting a desktop session. The segfault is said to be in plasma, not directly in KDE. Tried reinstalling (older versions of) plasma and kde, but nothing seems to help.

The crash can be reproduced every time.

 -- Backtrace:
Application: Plasma-werkgebied (kdeinit4), signal: Segmentation fault
