I cannot reproduce this working with the CVS repository, so I assume the problem lies downstream. It's very likely that your rsync mirror received an updated ChangeLog but that Manifest had not been updated yet. Please sync again and see if it still fails.
Yes, resyncing 30min later solved that. I don't know how devs and repoman play with the tree, but I still find that surprising that `partial' commits are possible.
