After looking at something related but not the same, I ended up with:

 ;; Do forward as MIME (the default), but don't show me the
 ;; MML.

 ;; Showing the MML causes decoding and recoding problems, where the

 message-forward-as-mime t
 message-forward-show-mml nil

No idea if this will help with the problem you see.
