Correct, and I made note of this in the patch I wrote.[1] The problem is
that the python3 version of the Cairo bindings doesn't know how to write
to sys.stdout/sys.stderr, which changed from from accepting str in
python 2, to accepting a byte stream in python 3.

At the time I wrote the patch, I reported this upstream [2], which has
been unresponsive.
