Now, in those test cases, a hg repository gets created that actually contains a "null" bookmark named "master". When the proposed fix for the problem is added, this bookmarks gets ignored. But at that point, remote-hg already determined that there is a hg bookmark named "master", and adjusts how it works accordingly -- when we then remove that bookmarks, things go awry.

Actually, scratch that, I just came up with a fix, and also tests. Will submit shortly.
I'd still like to know whether it is OK to submit further patches with (x?)failing test cases?
