[Mailman-Users] MM-2.1.2 shunting of message with unicode error

[Mark T. Valites]

Hi all - been a long time since I've been a member of, much less posted to
the list.

Since going to 2.1.2 this past summer, I haven't had a single problem with
it. I'm running it on Solaris 8, with python-2.2. I've also got James
Henstridge's spamassassin patch integrated into the setup.

I'm currently having a problem with one single list out of the 500 I
currently have here at my site. I had this same exact problem a couple
weeks ago with the very same list, but removing all traces of and then
recreating the list seemed to at take care of the problem until this week.
Right now, when one of the list members (who just happens to be my
department head...) posts to the list, her posts get thrown into the shunt
directory.  From the errors, I suspected that there was a problem with
MIME encoding of the message or attachment, but the shunting also occurs
when I sent a message with no attachment in plain ascii text
(charset=US-ASCII).

Attempting to unshunt them results in the following error:

I've dug through the mailman-users archive and the bug tracker on
sourceforge, but couldn't find anything that looked exactly like what I'm
seeing. The closest I found was:

http://sourceforge.net/tracker/index.php?func=detail&aid=871050&group_id=103&atid=100103

And also bug 834486 mentioned in the Changelog for 2.1.3 looked similar
to, but not quite what I'm seeing.

And suggestion are appreciated.
