I believe you'll find the underlying problem is that there is a message
in /var/lib/mailman/lists/<listname>/digest.mbox with a Content-Type:
header with a charset="Unicode" parameter. If you edit the dgest.mbox
file (possibly changing charset="Unicode" to charset="utf-8" or
deleting the offending message), that will allow the list to resume

As to which <listname>, it's the one that hasn't produced a digest
since this started.

Fix the digest.mbox (or just move it aside)

>2) What do I need to do to clear the problem that is causing shunting?

See 1).
