That implies that GnuPG doesn't have a copy of the signer's certificate.
If you set $KEYID to the hex version of the keyid you discovered, and
then do:

  gpg --keyserver pool.sks-keyservers.net --recv 0x$KEYID

then retry GMime on the message in question, you should get much more
information about the key.
