To me it seems this is not a problem of GitPython directly, as the user running GitPython doesn't seem to have permissions to remove a file from the filesystem.

You should be able to reproduce this kind of error by running git br -D changes/83/171983 as the user that showed the given exception.

Please let me know what you could find out..

You can watch the development stream on youtube.

Posting a stack-trace of the attempted deletion of a non-existent branch without any additional statement on how git-python would be involved puzzles me. After all, the question was if the user running the git-python script is actually allowed to delete a branch in terms of the required filesystem permissions.

From what I see, this isn't an issue of git-python, which is why it seems alright to close it.

This is coming a stack trace from Gertty, as stated in the first post, which uses git-python!

After all, the question was if the user running the git-python script is actually allowed to delete a branch in terms of the required filesystem permissions.

Yes - the same user running Gertty is the same user that owns that directory and all files under it.

Please, I would appreciate reopening this issue so we can continue to diagnose.

Unfortunately I don't believe this is an issue of git-python, as it looks like gertty wants to delete a non-existing branch but has no permission to do so. My guess is that gertty is running as a user who has no permission to alter the repository, for some reason.
I have repeated myself many times already, which usually shows there is a dead-end here.

My guess is that gertty is running as a user who has no permission to alter the repository, for some reason.

I believe this is incorrect - gertty is running as my user account and is manipulating a git tree that I own.
