Bug#440701: compiz: segfaults on startup

[David Förster <david@dfoerster.de>]

Hi,

I tried logging per ssh but didn't get much (recompiled compiz with 
DEB_BUILD_OPTIONS=nostrip):

(gdb) run --no-fbo --replace gconf
Starting program: /usr/bin/compiz.real --no-fbo --replace gconf
[Thread debugging using libthread_db enabled]
[New Thread -1210889792 (LWP 31801)]
/usr/bin/compiz.real (cube) - Warn: Failed to load slide: freedesktop

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1210889792 (LWP 31801)]
0xb7b766ee in ?? () from /usr/lib/compiz/libwidget.so
(gdb) bt
#0  0xb7b766ee in ?? () from /usr/lib/compiz/libwidget.so
#1  0x00000000 in ?? ()
(gdb)
