I can update an existing file just using repo.write. The README says that files not existing in the repo are created on the fly. However, that doesn't seem to be working?

Looks like a path problem, because I get these 2 errors back...

OPTIONS https://api.github.com/repos//undefined/git/refs/heads/master?1345134920700 204 (No Content)
GET https://api.github.com/repos//undefined/git/refs/heads/master?1345134920700 404 (Not Found)

Notice there is no username or repo and a double slash after github.com/repos.

Can you confirm if there is a slight bug here?
