The "unprocessed spam" files in qfiles/shunt should be deleted.

The traceback indicates it's not a digest.mbox problem. It is rather a
problem with the archive database for this list. The database is used
by pipermail to build the archive index files and appears to have
gotten something nasty in it (from the Subject: of a message?) on Oct

I would look at the archives/private/listname.mbox/listname.mbox file
and see if I could find a problem, e.g. a Subject: header with an
acute a (or something encoded as hex a0). If I could find it, I'd fix
it. The next step is to rebuild the archive and figure out what to do
with the shunted messages. Since the archiver runs outside of normal
message delivery, and since the pipermail archiving comes after
archiving to the listname.mbox file, my guess is all the shunted
messages have been delivered to the list and are in the listname.mbox
file. If this is true, stop Mailman, fix the listname.mbox file and
rebuild the archive from listname.mbox with 'bin/arch --wipe
listname'. Then you can start Mailman and just delete all the files
from the shunt queue.
