Possible error in animate.py after commit cc617006f7f0a18396cecf4a9f1e222f1ee5204e

Hi

I've just checked out the newest version of matplotlib from github using git (version d5b078b ) and my Animation files didn't work any more.
The error is given below.
I reverted to version cc61700 which gave the same error. By reverting to the one before ( edb1526 ) it worked as before.

Is this a bug?

I'm sorry, I didn't see #2012 which covers the reason of the error.
