In the above, v is the value part of one of the (header_name,
header_value) tuples returned by msg.items() where msg is the incoming
message instance. Both the name and value should be strings.

To the best of my recollection, I have not seen this issue before.

Please send me a copy of one of the shunted .pck files.

Also, are any of your patches to Python's email.message.Message class or
Mailman's Message.Message class.
