The problem is that you are writing a compressed PNG data file into the
buffer. The pygame 'fromstring' and 'frombuffer' functions expeect a
string with raw pixel data.

I've lurked on the cairo list every once in awhile, I'm pretty sure
there is a way to get this type of string from the cairo surface.
