Exactly.  I have some experimental code in Mailman 2.1 which should be
able to retroactively fix such problems in an mbox archive file, along
with problems with unquoted From_ lines.  The downside: it requires
regenerating the entire archive, and it messes up existing urls to
articles.  Upside: it should assign more permanent urls to articles,
based on Message-IDs.
