To add a data point, this message was a "reply-to-all" in Thunderbird 3.1.10.  It included Tom's address, ignoring the reply-to: header.

Considering Thunderbird's popularity, just using a reply-to: header won't solve the duplicate message "problem".  This is especially true on open mail lists, like those at kernel.org, where "reply-to-all" is expected of participants.
