Perhaps repository was set up in an unusual way by hand (i.e. not by a clone), such that: 1. you have HEAD pointing at a branch (e.g. 'refs/heads/master'), 2. which does _not_ exist yet (i.e. no 'refs/heads/master'), 3. yet you have a tag that you can try to detach your HEAD to (e.g. v2.6.20). ... well that was my initial guess, but even after setting up such a funny repository by hand, I cannot seem to reproduce it. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
