I ran into this issue last week, but hadn't had a chance to work on it. It's hit others aswell:

• os.getlogin() - Inappropriate ioctl for device (mod_wsgi) gitpython-developers/GitPython#39

The pull request is exactly the direction I was going to go with it, so thank you for that! I'm traveling this week, but will work on pushing this out to stable branch next week.
