Errors when updating an old git.git repository

Greetings,

I just did "git-clone git://git.kernel.org/pub/scm/git/git.git". git-pull in the resulting repository gives "Already up-to-date." and "git-pull --tags" does the same. Just what I'd expect.

Before I did that, I had an old (several months) git.git repository laying on the hard drive and I updated it with "git pull". It complained something tag related and I tried again with "git pull --tags". Now I'm in a situation where "git-pull --tags" gives "No changes." but plain "git-pull" gives me this:

Already up-to-date.
-------------------------------------------------------------------

If I run either git-pull or "git-pull --tags" again, I get the same results.

Since updating a freshly cloned repository doesn't result to such an odd behaviour, I assume this old repository is broken somehow. If someone wants to inspect it, I can make it available via web.

I'm using git 1.4.4.3 on Debian GNU/Linux.
