Fails to build documentation

When building documentation for 0.5.1 (from the tarball from GitHub) for the package for openSUSE I got this failure:

Oops, I broke that. I’m out now but can fix later today.

Reminder for me: add tox command for building the docs and running doc8

Fixed in ccf815d and deployed to PyPI as v0.5.2
