Fix MIME digest attachment

[tkikuchi]

ToDigest.py in Mailman 2.1.1 was improved in handling
plain text digest but there was a side effect in MIME
digest.
We should now use copy of Message instance because the
original is scrubbed afterwards.

This patch is only 3 lines. Please check if your
Handlers/ToDigest.py was properly patched. I can't see
anything related to this patch from your traceback log.

The patch looks good, so I'm closing this in anticipation
that testing will work out.

I'm with tkikuchi though, I can't see how this patch could
possibly evoke dwighternest's bug.

I'm still getting this:

2003-October/000025.html whenever my users post HTML
messages.

Thanks, M.
