How to reproduce
-----
0. Panel looked to be half oxygen theme half air theme divided in middle of screen.
1. Tried to fix by changing from Air to Air-for-netbook theme in System-Settings->Appearance->Style->Workspace
2. Panel and background disappeared. Alt-tab'ing and alt-f2 still worked.
3. Running plasma-desktop got the panel and background back.

Comment 2 Eirik Thorsnes 2010-03-06 11:36:28 UTC 
Correction: the crash occured when switching BACK to Air from Air-for-netbook theme. Just reproduced the crash again now.

I also tried switching from Air to Oxygen theme. This time kwin crashed with signal 7, should I report separately?
Comment 3 Kevin Kofler 2010-03-06 16:05:09 UTC 
No, those SIGBUS issues are all the same bug, we have tons of duplicates already. The stacktrace has always one of 2 related functions of the same class on the top (KPixmapCache::mmapFile or KPixmapCache::invalidateMmapFile, most times the former).
