Thenk there are some _other_ differences between your situation and what I
can construct from your problem description:

    It seems to me that:

       $ git co topic
       $ git rebase --onto master topic~2 topic

    Used to do the job and rebase the topic branch as expected....

which I tried myself before giving you a reply, and I didn't end up on a
detached HEAD.  But I cannot guess what that difference you are not
telling us is (and you probably don't know it either, I suspect).

Writing reproducible test case would be a great way to diagnose this.
