Sure.  I've just installed a fix.  In the above message, the
first part incorrectly inherited the default type as
"multipart/signed".  It should be "text/plain".

And the second part is surely "application/pgp-signature"
which current rmailmm doesn't know how to handle, but I made
the body shown as a text by typing RET.
