Additional info:

Possibly fixed with af63993 ? This handles the KeyError using get that defaults to None and seems there is some difference in CommonMark spec markdown files as I can see from the commit. Can you try installing sphinx from master as below?

pip install git+git://github.com/sphinx-doc/sphinx.git@eb44c73b81ff4e603d9452018d145ff3c204f71f

Thanks
