I suggested on IRC to try this (I reproduced the error)

mkdir test && cd test && \ git-init && \ git fetch http://intellinuxwireless.org/repos/ipwraw.git master:master

and it works. Ok, fist I thought the error is in another branch, but

git-ls-remote http://intellinuxwireless.org/repos/ipwraw.git 7e85b2032a864fcfe489085b768eea4b3a3a9d0b refs/heads/master 7e85b2032a864fcfe489085b768eea4b3a3a9d0b refs/heads/origin 7e85b2032a864fcfe489085b768eea4b3a3a9d0b refs/tags/ipwraw-0.0.1 7e85b2032a864fcfe489085b768eea4b3a3a9d0b refs/tags/ipwraw-0.0.2

there is no other branch, at least as I could see.

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".

The above does explain the breakage. The script that created snapshot tarballs for ipwraw was written was copying .git/HEAD to the tag name in .git/refs/tags... at some point .git/HEAD changed from being an actual symlink to master to being a normal file containing 'ref: refs/heads/master'

I believe I have fixed it now.

Thanks, James
