Application: kde4-window-decorator (0.0.1)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
I launch compiz with the compiz fusion tray icon (launched by "fusion-icon --no-start").
Then I choose KDE4 window decorator instead of GTK decorator.

KWIN segfaults directly, systematically.
This has happened since all beta versions of kde 4.4 (can't remember if in 4.3... long time ago :) )

The crash can be reproduced every time.

 -- Backtrace:
Application: KDE Window Decorator (kde4-window-decorator), signal: Segmentation fault
