Comment 4 for bug 620684

I was hit by this very same problem. See the relevant bzr.log entries attached.

As you can see, I was able to successfully run an export --per-file-timestamps, then committed a revision. After that I Ctrl-C'd a regular export, and after that I was still be able to export without --per-file-timestamps, but not with it anymore.

reconcile didn't help. Do you have any ideas how I could restore the repository/branch into a working state?
