Comment 27 for bug 541626

So I keep running into this as well, using git-bzr-ng

I have noticed that it seems the map files are being corrupted, or at least no longer ordered, and that new entry revision numbers don't follow the sequence

Eg.
  .git/bzr/map/master-git file starts in a clean ordered state (tail below)

but after trying to do
  git bzr push

the map file is completely out of order (tail below)

:1503 c1bd59e54332b7d021eee3e7bd44f4a8afb76673

and after sorting I find 2 new entries, that seem to
correspond to the two commits I am pushing but their
revision # seem to be incrementing by 3 instead of 1

The .git/bzr/map/master-bzr file sees the same type of reordering but does not gain the 2 additional entries
