Re: cairo-xlib-surface.c:401 _swap_ximage_to_native: Assertion `N OT_R EACHED' failed.

Cairo is a (very nice) 2D vector graphics library, and yes it is
fairly recent.  As of version 2.8 (I believe), GTK+ uses Cairo to do
most of it's drawing, etc.  So it's now a dependency of GTK+.  Did you
upgrade GTK+ recently?
