Bug 5196

I can't get any recent Gtk applications (using Gtk 2.8.6) to work when
forwarding the DISPLAY of the applications to any SGI Octane's we have
here.  It's running IRIX/6.5.15f.  The application is running on a linux box. 
Cairo 1.0.2 is installed.

I can supply other details if needed. 

It seems to be failing in one of the cairo functions.

Backtrace of one of my applications:
