Nope. There's only 2 patches, one for linebreaking (see
http://bugzilla.gnome.org/show_bug.cgi?id=131625), one for caching
extents of the drawn area + our configuration (parameters passed to

I think what happens here is that gtk-demo fails in initialization and
therefore has invalid data passed to pango functions and Pango complains.
