It's kind of a late reply on my part, but I agree. Your situation is kind of unique, because your file in question hasn't changed, but even under valid changed-conditions, the file is skipped during backup. I think that at least, rdiff-backup shouldn't just say that the file was changed during backup, but also that it's not backed up this run. I think an option to rdiff-backup like "--retries-on-file-change [number]" would be welcome as well, perhaps with a 2 second (or so) pause between each try. And, an option to queue the files which have changed for retrying at the end of the backup would be convinient as well, because an immediate retry could still result in a file-has-changed situation. This option could be "--queue-retry-changed-files" or something. In any case, the changed-file behaviour needs some reconsideration, in my opinion, to prevent data-loss.
