Appl that uses Compositor extension crashes XWin

[Maarten Boekhold]

Hi,

I'm running X.Org 6.8.1 with the compositor extension enabled 
(+extension Compositor). I compiled the CVS version of xfwm4 (the 
windows manager of XFCE, http://www.xfce.org) with compositor support. 
However, every time I start xfwm4, the X-Server crashes immediately. I 
can't find any log to research what's happening, and nothing is shown on 
the stdout of XWin.

Can anybody suggest how to research *why* this crashes? I'd like to see 
it fixed :)
