Hi everyone, I got a strange report over at http://bugs.debian.org/316375 that I'm trying to track down. I'm not sure if this is a bug in darcs or tla, but I'm leaning towards darcs as the culprit. There seems to be a non-deterministic difference in behavior of darcs diff on a repository converted from arch to darcs using arch2darcs (which is nothing more than a thin wrapper that invokes both tools via their respective command-line interfaces).
Any help any of you could provide would be great.
