RhodeCode CE/EE

We installed the update to RhodeCode Enterprise 4.11.5 last night (we were previously on 4.10.6, I think). Today, one of our users reported an error when trying to create a pull request on a Mercurial repository. Digging into the log files, I found these errors logged:

From enterprise.log:
