Incorrect behaviour with MML and Gcc:?

[Nathan Williams <nwilliams@primeon.com>]

        I recently switched to pgnus 0.84 from a release version so
that I could use all the great new MIME goop. While it mostly works
well, I've found the following problematic situation: If I compose a
MML-based message and keep a copy with the Gcc: header, the copy that
is kept is the pre-translated MML, not the actual MIME text. This is
mostly a problem with attachments, since the actual file I told it to
insert may not have been one I planned to keep outside of my mailbox. 

        I'm not up on the zen of MML and MIME in Gnus, so I'd
appreciate other people's sense of whether this is a bug.
