This sounds like you (or dim?) accidentaly amended that commit (which
changes the committer and results in the warning), and a rebase would
indeed have fixed that. If the first patch conflicts this can happen
because dim apply-branch doesn't bail out correctly. Or at least did
in the past, I recently fixed that in

    dim: make apply-patch fail again

If your dim didn't have the above commit and you had a conflict it's
all explained. Otherwise I'm not sure what's been going on ...
