Public bug reported:

Binary package hint: compiz-core

I upgraded all my compiz packages to the latest hardy version today to
see if there were new features, but instead compiz dies with a
segmentation fault for me whenever I try and start it. Version info:

$ apt-show-versions | grep compiz

$ uname -a
Linux ****** 2.6.24-8-generic #1 SMP Thu Feb 14 20:40:45 UTC 2008 i686 GNU/Linux

My computer is a Dell XPS M1710 laptop with an NVIDIA GeForce 7900 Go
GS, using the 169.09 drivers.


If compiz is started from the System -> Appearance -> Visual Effects tab, I 
simply get "Desktop effects could not be enabled".

If started from a terminal by typing "compiz", I get this:

$ compiz
Checking for Xgl: not present. 
Detected PCI ID for VGA: 01:00.0 0300: 10de:0298 (rev a1) (prog-if 00 [VGA])

Starting gtk-window-decorator
Segmentation fault (core dumped)

Looking at the script, it is compiz.real that is segfaulting. I have
attached a backtrace obtained with gdb (not really sure if I did it
properly though). The segfault occurs in XGetXCBConnection.
