Here is the ~/.bzr.log of a push in question. This is with Martin's patch applied. I also seem to be unable to bzr branch this branch now. When I try, bzr seems to just sit there forever, slowly leaking memory. However, merging those branches into another seems to work ok still. Should I file a separate bug for that?
