It turned out that the problem really was that I didn't end the
gdk_pixbuf_save() call with a NULL.
I also realize that I incorrectly used GError, although in this case it
didn't cause any errors.

Looks cool. I'll use your function.

Absolutely!
Thanks everyone for the help! This is one the most helpful communities
I've ever came across.
