I don't know how this would happen; it would be great if you could
find reproduction steps and send them in, or if you had the complete
git rebase log, some of which probably explains the problem.

You can probably recover your pre-rebased repository using 'git
reflog'.  Look through the reflog to find the commit you want, then do
something like

    git checkout whatever-the-commit-id-was-that-you-got-from-git-reflog

and then optionally

    git checkout -b master

Good luck.
