The particular message you dumped looks OK. We've possibly got more
than one issue. I'd still like to see the rest of that traceback.

The most likely cause of this immediate problem in Mailman 2.1.5 is a
bad message in the list's digest.mbox file. If you look at
lists/list_name/digest.mbox with an editor, and you can't immediately
see a 'problematic' header that you can fix, rename the digest.mbox to
something else. This will probably allow normal processing to resume.
You may be able to unshunt the shunted messages, but there is likely
still a bad one there that will cause the problem all over again.

It may also be difficult to properly recover the digest.
