well, here is a patch which solves this problem for me:

could someone with CVS rw access apply this if you find it correct?

BTW, i just noticed that the Lines: header generated by gnus is
incorrect. So the old bug with Lines: header is still there. :-(
Could someone please fix it? (calculate Lines: NOT for MML message,
but for a MIME message)
