>Description:
Probably the same as
http://bugzilla.clutter-project.org/show_bug.cgi?id=2345
and 
http://www.mail-archive.com/mesa-dev@lists.freedesktop.org/msg03324.html
These indicate an issue when clutter tries to create a 1x1 drawable to find things out about the context.

As far as I can tell, any clutter program segfaults when run.

Normal OpenGL programs seem to work fine still.

Some installed package versions:
clutter-1.4.0
dri-7.4.4,2 

I've tried a bit poking around at some ports to find out what's going on. Any help would be appreciated.

I am running on an Acer Aspire One netbook, with an onboard intel graphics card: 945GME
