I've checked everything in the most applicable FAQ (http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq03.014.htp). In the error log, I keep getting "Uncaught runner exception: len() of unsized object" (the full log entry with Traceback is at the bottom of the email).

The error is because of a badly formed mime multipart message. The
Mailman 2.1.6 version of Scrubber.py contains the following insert
before the ' size = len(payload)'.
# XXX Under email 2.5, it is possible that payload will be None.
# This can happen when you have a Content-Type: multipart/* with
# only one part and that part has two blank lines between the
# first boundary and the end boundary. In email 3.0 you end up
# with a string in the payload. I think in this case it's safe to
# ignore the part.
if payload is None:
size = len(payload)
The reference to email 2.5 is the Python library email module.
These errors put the message in the shunt queue (qfiles/shunt/).
Presumably the message or some residue of it is still elsewhere,
probably in lists/<listname>/digest.mbox, causing this error to occur
for each new message.
You could install the above code in Scrubber.py. If so, be careful -
the above isn't indented the right amount and indentation counts.
Otherwise, you could try to identify the bad message in the shunt queue
and delete it and also edit digests.mbox to remove it from there too.
Then you can probably run bin/unshunt and be OK, or if you just want
to get things started again without worrying about lost messages, you
can just remove the digests.mbox and delete the messages from the
