Xfwm4-svn crashing with composite enabled

[Landry Breuil]

Hello list,

I'm still playing with xfce-svn on OpenBSD 4.0-beta, and recently started
using Composite with XAA acceleration (i810).
Xfwm4's composite manager works fine, but crashes often, generally when
spawning or closing a new window in firefox (login/passwd sub-window for
example) or thunderbird.

Here is the weird trace i get with the core :
(gdb) bt
#0  0x0beda9f5 in kill () from /usr/lib/libc.so.39.2
#1  0x0bf13323 in abort () at /usr/src/lib/libc/stdlib/abort.c:65
#2  0x07b54f7b in g_logv () from /usr/local/lib/libglib-2.0.so.1000.3
#3  0x07b54f9f in g_log () from /usr/local/lib/libglib-2.0.so.1000.3
#4  0x1c024ed1 in handleSignal ()

Is it more a xfwm4 problem, a composite problem, or glib problem ?
