I'm seeing the same thing. It works OK as long as the body of the 
message is us-ascii, but if it contains characters like æøå 
(iso-8859-1) the message  is printed in the archive as quoted printables 
(litteraly) and the link is mangled like reported by the OP.

The message is sent fine to the list, _unless_ msg_footer is empty. If 
it is empty the message mailed to list also contains quoted printables. 

(If scrub_nondigest is set to no, archiving works perfectly fine with 
iso-8559-1 characters)

Anyone else seen this?
