The problem there is that Gnus is not adding the header:
Content-Transfer-Encoding: quoted-printable

It also messes up certain things by decoding the plaintext messages as
if it were quoted printable before signing and then re-encoding.

Strangely enough, this only seems to be broken in CVS Gnus.  Non-CVS
Gnus doesn't have that problem, so it must have been broken recently.
However, I didn't see any obvious reason for the problem when looking
at the sources.
