I wish you'd tried this before the 0.8.3p1 release!

That happens when the fetch fails, for whatever reason.  Amber has
suggested that a better solution would be to use remote branches, so
e.g., we'd log master..origin/master instead of HEAD..FETCH_HEAD.  I
think that might improve the situation a little bit (after a failed
fetch, you'd just get zero revisions).
