This is very strange. It is saying that in the statement
evictions = db.setdefault('evictions', {})
in Pending.py, db is a Message object. I think the only way this could
happen is if the lists/LISTNAME/pending.pck file is a pickled Message
object rather than a pending database. How that would happen, I don't know.
You could dump this file with Mailman's bin/dumpdb and see what it is,
but the simple fix is just remove the file.
