Xorg composite extension makes xine/kaffeine crash

Hello,

I have the Xorg composite extension enabled to enjoy things like 
transluency with KDE, I do not use an OpenGL window manager, Beryl or 
similar, just plain KDE 3.5.7.

Now, when I start kaffeine to play a video file the whole X server 
crashes. Not just kaffeine, the whole X server gets killed immediately. 

The only message at syslog is "kdm[7543]: X server for display :0 
terminated unexpectedly"

I does not matter what output driver I use with xine/kaffeine, xv or 
xshm, the X server crashed immediately.

Since I can reproduce this behaviour I am sure it has to do with the 
composite extension. When disabled, everything is fine.

Is this a known issue? Any workaround available? I don't wanna drop 
composite because I like these nice desktop effects ;-)

Thanx

System: openSUSE 10.3 (32 Bit)
Xorg 7.2
nVidia 6200 based AGP card
latest nVidia proprietary driver (169.12)
kaffeine 0.8.5
xine-lib 1.1.10.1
