GitError, TypeError: not all arguments converted during string formatting

[toutpt]

The typeerror comes from here, the fix is trivial:
https://github.com/fschulze/mr.developer/blob/master/src/mr/developer/git.py#L158

output = action(**kwargs)

return self.git_checkout(**kwargs)

Yeah, the branch is irrelevant for the error message, so this is the fix:

raise GitError("'git branch -a' failed.\n%s" % stderr)

But I wonder how you got it to fail at that point.

This is quite a weird context:

I'm currently try to use git's post-recieve hook (server side) which launch a shell script in background (using nohup script). When the script is launch by git it seems it delete the STDIN so mr.developer fails on some repository only. We have tried to set threads to 1 but it doesn't fix the issue.

To fix our issue we just change the way to trigger the build so now the post-recieve just create a file (touch) and a cron launch our build if a file exists.
