I'd guess that there may be some sort of "ref" still pointing at the "cleanup" branch which presumably was, at some point, checked out at "<my source dir>". Digging through the code[1,2,3] suggests that you might have some stale state from a rebase, bisect, or other sequencer operation which still references the "cleanup" branch. [Cc'ing Phillip who is probably much more familiar with this code than am I.] By the way, it's not clear from your initial report what you mean when you say "then the remote deleted the branch". Also, did you fetch and/or pull from the remote after that?
