Hey @mibaumgartner!
Thanks for sharing!
Quickly, you can remove the .git folder or uninstall GitPython to avoid the issue. That is certainly a pain to manage.
Probably a better approach is to upgrade git. Based on that version, that release happened in 2013. I believe if you have 2.7 or higher (released in 2016), it should not have the issue. Of course, upgrading to the latest is good and probably best.
Is the upgrade something you can do? We’re looking into checking the version of git before performing our checks.
