Comment 3 for bug 265707

I found a similiar problem and traced it down to the
code in ../Mailman/MailCommandHandler.py:

...
        # Note further that some misconfigured list managers
don't include any
 # of these clues, so there's little we can do to break
loops in that
 # case, except throttle the number of responses sent to any
one
 # requester in a day. That's a job for MM2.1.
 #!wig:org: precedence = msg.get('precedence', '').lower()
 precedence = msg.get('precedence', '')
 #!wig:org: ack = msg.get('x-ack', '').lower()
 ack = msg.get('x-ack', '')
 beenthere = msg.get('x-beenthere', '')

Apparently the message mailman received (subscriptions) did
not have the precedence and x-ack header line. Removing
the .lower() helps (but I have no clue about python,
so i guess that was only a short term fix).

Further processing of files in ~mailman/qfiles was failing.

Errormessage (from ~mailman/logs/error):
