Unable to issue subkey revocation

[marqueandreprisal at duck.com]

About being careful not to post the private key. I would be embarrassed 
to accidentally upload my private key. I recall PGP 1 having a "keypair" 
with a fingerprint of the private key and public key however in this new 
gpg2 it appears the same fingerprint identifies both the seckey and 
pubkey. Is the long ID actually a fingerprint of the pubkey even when 
identifying the seckey within gpg2?
