bzr crashed with NoSuchRevision in _get_revisions()

[Ted Gould]

Binary package hint: bzr

It seems that bzr lost a revision. It's in the history, but doesn't exist. Here's the error I get when trying to do a diff:

$ bzr diff -r 8541 > diff
bzr: ERROR: bzrlib.errors.NoSuchRevision: KnitPackRepository('file:///home/ted/Development/inkscape.bzr.old/.bzr/repository/') has no revision <email address hidden>

*** Bazaar has encountered an internal error. This probably indicates a
    bug in Bazaar. You can help us fix it by filing a bug report at
        https://bugs.launchpad.net/bzr/+filebug
    attaching the crash file
        /home/ted/.cache/crash/bzr-20091221192407-28090.crash
    and including a description of the problem.

    The crash file is plain text and you can inspect or edit it to remove
    private information.

This can be recreated from your own home using the following:

$ bzr diff -r 8541 lp:~ted/inkscape/newdevbuild > diff
bzr: ERROR: bzrlib.errors.NoSuchRevision: KnitPackRepository('bzr+ssh://bazaar.launchpad.net/~ted/inkscape/newdevbuild/.bzr/repository/') has no revision <email address hidden>
