Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.32.3-rsbac i686
Distribution: Ubuntu 9.10

-- Information about the crash:
it seems old oxygen themes make the plasma desktop crash (and kwin too)
only the default theme works properly

the crash happens when i use e.g. glassified (from kdelook), and move a plasmoid around
also happen when i set specific settings, eg, widgets backgrounds = oxygen, rest = glassified, boom :)

i suppose there's something not handled properly in the configuration

The crash can be reproduced every time.
