[Mailman-Developers] 'empty module name' error and shunting

[Nadim Shaikli]

I've seen a number of posts (courtesy of Google) about this topic,
yet not a single one noted a solution.  All either were resolved
with,

 1. upgrade and it will go away (I have the latest of everything)
 2. "this only happens on spam (bad header), don't worry about it."
 3. you are using a RH RPM install that is broken.

Well, in my case I'm on a debian system (code via apt-get) running
mailman-2.1.2-6.  I have about 12 mailing-lists all seem to function
without an issue except for one.  Anytime anyone mails to it, the
message gets "Shunned" and I see this error in the log/error file
(mind you the message is obsoletely fine - its as though there is
lock someone that is forcing all legit messages to be shunned).

If I try to 'unshunt' the message - nothing happens and it simply pops
back into the qfiles/shunt dir.  I have hoards of people waiting for this
to get resolved and I've tried asking anyone who would listen on IRC
(irc.freenode.net #mailman and/or #debian) to no avail.  The website
was no help at all (there is no mention of 'shunting' even and alot of
the info is rather dated).

Could someone please lend a helping hand _ASAP_ ?

I'm not on the list, so please CC your replies.

Regards,
