Summary: Attachments with ' just hang

Initial Comment:
If someone sends an email with the character '
in the subject or attachment name mailman hangs. 

after deleting the ' in the attachment name in
/usr/local/cpanel/3rdparty/mailman/lists/list_name/digest.mbox
the next message is delivered (but this message isn't
delivered!)

Apr 11 23:04:22 2006 (60899) Uncaught runner exception:
need more than 2 values to unpack

This was working fine before a recent upgrade with
mailman/python and still works fine on other servers.

I am unable to duplicate this error with various versions of
Python's email library. I am using an attachment with the header

Content-Disposition: attachment;
	filename="cal'dar.doc"

If the one that fails in your case is different from this in
any significant way, please post it.

I'm not sure if this is a 2.1.6 bug or a cPanel bug, but it
seems to be fine in 2.1.7 since I have now received copies
of this bug report, its two updates, the 149967 report and
its update (a total of 5 messages) from the
mailman-coders at python.org Mailman 2.1.7 list, and they all
have subject

[ mailman-Bugs-1469962 ] Attachments with ' just hang

(or the same with 1469967). I.e., the same messages you
receive directly from sourceforge.net are also posted to
mailman-coders at python.org.

In any case, if you want to post the full traceback from the
error, either here or directly to me, I will try to
determine the problem and suggest a fix for 2.1.6.
