I was worried about accepting the changes without a Mac to test them on,
and hoping that Michiel de Hoon (the Mac backend author) would have some
comments. Maybe we can convince one of the other developers on this
list who has a Mac to have a look.

Can you file an issue for this in the matplotlib-py3 github project?
I'm busy getting the matplotlib 1.1.x release finished up at the moment,
and don't have a working environment for Python 3 right now. I'd hate
for this bug to fall through the cracks.
