Right, I always forget about that one.. Maybe we should have a lint for this?

Anyhow: I'm not sure why, but the tests here fail. I figured it doesn't matter much though, considering it's part of GitPython, which has a way bigger testing suite that IMO covers the gitdb library enough to allow us to skip this here.
