BadWindow error with compiz-fusion

Hi all,

I have been plagued with a BadWindow error in compiz-fusion on my 
machine for a while now.  I went to the compiz developers first, and 
after no solution over several months, they've punted it to you.  Xine 
works just fine using fvwm, just not in compiz-fusion.  I'm running a P4 
with a 6800GT nVidia using the proprietary driver in Ubuntu's Gutsy 
repository.

Here's the error:
This is xine (X11 gui) - a free video player v0.99.5cvs.
(c) 2000-2006 The xine Team.
xiTK WARNING(_x_error_handler:258): X error received: 'BadWindow 
(invalid Window parameter)'
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 20 (X_GetProperty)
Resource id in failed request: 0xc00051
Serial number of failed request: 42
Current serial number in output stream: 42

It happens with all video drivers.

Here was my post on the compiz-fusion forums:

I'd greatly appreciate any help.

Thanks!
George
