bzr crashed with NoSuchRevision in _get_revisions(): CHKInventoryRepository('file:///home/username/src/nux/.bzr/repository/') has no revision <email address hidden>

Hi,

I tried using bzr-builddeb 'import-upstream' command to update the sources of a debian package branch with the a new upstream version. I got a NoSuchRevision exception. I'm not sure if I'm using 'import-upstream' the right way, but I guess it shouldn't crash like this anyway.
