[cairo] GTK Apps crash in fbFetch on Tektonix X-Term

[Nate Byrnes]

Hello,
	I recently upgrade to dropline gnome 2.12. In this release, it seems
that Pango was upgraded to include pangocairo.  After the upgrade my
Tektronix X-Term could no longer present the GDM greeter.  As I
troubleshot I discovered that the GDM greeter process was segfaulting.
I then tested running various X apps from the server with my DISPLAY set
to the X-Term. X apps that didn't use Gtk seemed to work, where
Gnome/Gtk apps were crashing.  I then did a dependency comparison (which
seems unnecessary now) to find common libraries. Then I used gdb to run
the applications. All the applications were segfaulting on a call in
libcairo. I have included the gdb output below.  Please let me know how
I can help fix this (my wife is the primary user of the X-Term and is
less than thrilled with my "upgrade"). 
	Regards,		
	Nate

ps. The Gdk-CRITICAL errors always seem to occur, even when the program
is working.
