Redmine

We have a little git hook that calls "rake redmine:fetch_changesets" at each successful push in our git server.

All functioned well for a few months, then we got the error message listed below.

The particular push that triggered the error is not different in any particular way. It is a merge and it touched an above average number of files, but such commits we did have before in this repo.

There is no visible adverse effect in the Repository page.
