fwiw, i believe that the current master
( 627460d7bbbb6b95a07084c2b6fc7f647a5547e1 ) *is* broken on systems with
older gmime.

In particular, on debian buster, i see:

T356-protected-headers: Testing Message decryption with protected headers
 FAIL   verify signed PKCS#7 subject (multipart-signed)
	sig_uid: object not found: data[0][0][0]["crypto"]["signed"]["status"][0]["userid"]

My [PATCH v2/2 v2] in this thread (sent shortly) should resolve this
situation.  Then, i'll send a rebased version of the full S/MIME series
in a new thread.
