[Bug 826962] Re: bzr crashed with ValueError in version_file()

[Martin Pool]

It looks like bzr's trying to re-reversion a file with a file_id of
None.

** Description changed:

  This happened while doing a one-file revert in a changed repository.
  
  The repository history might have had some impact:
  
  1) it was a subdirectory in a larger repository, from which it has been split using "bzr split"
  2) there are several uncommitted changes and I'm trying to revert one of them.
