Nice!!  Where did you learn that trick?  pb.pixel_array is not
documented at
http://www.gnome.org/~james/pygtk-docs/class-gdkpixbuf.html.

This is great to know because I can use the same approach to port
image handling to gtk once I get that up and running.

FYI, your patch was line wrapped but it was simple enough to apply "by
eye".
