Hi,

GitPython doesn't work with GPG signed git commits. It errors out:

    remote: Traceback (most recent call last):
    remote:   File "./hooks/post-receive-chained.d/post-receive-fedmsg", line 46, in <module>
    remote:     commits = map(_build_commit, lines)
    remote:   File "./hooks/post-receive-chained.d/post-receive-fedmsg", line 31, in _build_commit

There's a pull request open at upstream's github instance, but since upstream is unresponsive, it hasn't been accepted yet. 

https://github.com/gitpython-developers/GitPython/pull/124

Unfortunately, master and the 0.3 branch are quite different and seem to be developed in parallel, so a patch isn't very simple to extract from the repository. Commit 62ecd6c is the latest commit with the gpg fix:

https://github.com/sugi/GitPython/tree/gpg-sig-support

It's 2 commits ahead of master.

Thanks,
Warm regards,
Ankur
