If it was an older format, I could see having race conditions (sftp
locks were different than local locks in bzr-0.7). But that hasn't been
the case for any of the metadir (newer than 0.7) formats.

Go ahead and send me copies of the .kn* files, just in case there is a clue.

Unfortunately, no, we don't have any sort of log of changes, other than
looking through everyone's ~/.bzr.log files :)

We have worked quite hard on the model to prevent any sort of breakage
outside of a broken lock. Is the project public at all?

What I'm also curious about is the commit logs for the involved
revisions, which might indicate what sort of concurrency was being
attempted. (Why were 2 people modifying the same file, and why doesn't
the repo care that one of them has now been removed).
