I haven't narrowed it down yet but is certainly during message-do-fcc.
It's hard to tell because the work takes place in a temporary buffer but
I'm currently looking at the code that does:

    (when file
      (with-temp-buffer
        (insert-buffer-substring buf)
        (message-clone-locals buf)
        (message-encode-message-body)

And wondering how that might of changed.

Any idea how to examine the current with-temp-buffer while stepping
through in edebug?
