But there is no signature.  It is a proper certs-only message which as
far as I remeber is weel defined by CMS.  gpgsm simply didn't showed the
message because you gave a data file.  I improved that diagnostic
meanwhile.

I would appreciate if someone else with CMS knowledge could look at that
signature to check my findings.
