What surface are you rendering to? Some of the recent reworking
of the font code paths in Cairo really aren't right for the way that
the win32 font backend works, and certainly haven't been tested
there, but I don't see anything offhand that would cause problems
rendering to the win32 or image surfaces.

Can you provide a backtrace?
