Interesting.  Yeah, this shouldn't happen.

What is the exact command you use to get the above output? Is your repository public (which would let us reproduce it) or can you reproduce it by creating a small artificial test repository?

For comparison, did some previous version of git work ok in the same scenario, or is this the first time you've tried it?
