Description Elijah Newren 2008-05-23 23:46:53 UTC 
Revision 3714 seems to work fine for me; revision 3715 (Iain's changes to add basic public compositor API) does not.  With the latter revision, metacity dies during startup--the stacktrace I captured is:

Also, why are we connecting to bug-buddy?  It turned out to be nice for me because it provided a nice little deadlock that allowed me to more easily connect with gdb from a remote machine, but I'm hardly the person to optimize for.  :-)

Whoops forgot to check for NULL compositor before dereferencing.
Fixed in revision 3723

As for bug-buddy, I dunno, it doesn't kick in here and I didn't do anything to add it.

Sweet, thanks for the quick fix.  :)
