Aha! That's it.

I guess you've garbage-collected your repository, either by hand ('git 
gc') or automatically, and that there is a file .git/packed-refs that 
contains a line like this:

8e22067d59f59ee3a39f5d4f95c27e8ea3c935d6 refs/heads/master

If so, someone (perhaps you?) needs to modify the 
emacs-repository-get-version function in lisp/version.el to handle this 
situation.
