There was a thread on this bug in one of the GTK+ development lists
a short while ago, and Owen Taylor fixed the problem in the GTK+ 2.8.0
sources that caused the black areas and assertion. Perhaps the fix
is still in CVS--but I've deleted the original message so I'm not
sure. Take a look through the GTK+ mailing list archives.
