There seems to be another ABI diff between 2.2 and 2.3.x:

   int gnutls_openpgp_keyring_check_id (gnutls_openpgp_keyring_t ring,
-                                      const unsigned char keyid[8],
+                                      gnutls_openpgp_keyid_t keyid,
                                       unsigned int flags);

Maybe there are more, it seems the gnutls_openpgp_keyid_t change isn't
backwards compatible:
