If you are willing, would you like to file a PR against the v1.2.x branch?

I'm not exactly sure how this has fixed itself, but now the above
command returns nothing (on 1.2.0 -doc package):
$ cd /usr/share/doc/python-matplotlib-doc/html/ && grep -r 'Exception

$
Hence closing this report.

I'm giving the closing keynote at PyCon Canada today, can I announce
1.2.0 offiical with py3 support then? It would be a fitting tribute
to John and the amazing work you have all put in moving the project
forward!
