The repository is seriously broken. If you try wget to see refs/tags/* files, you will find out that they are not even tags; they are symrefs and both point at the master branch.

I do not think the Porcelain-ish shipped with git creates symref in refs/tags/, so it was done by somebody playing with symbolic-ref by hand perhaps?

I'd suggest James to do delete these bogus refs/tags/* files and tag the correct commit with "git tag".
