imported smart-card keys

[Alex Mauer]

OK, I'm getting frustrated with the interaction with the smart card.

I have generated a new ElGamal encryption key, 0x16AF3873.

$ gpg --edit-key 51192ff2
gpg: NOTE: THIS IS A DEVELOPMENT VERSION!
gpg: It is only intended for test purposes and should NOT be
gpg: used in a production environment or with production keys!
Secret key is available.

OK, so I have exactly one valid signing key available on this machine
(RSA 4A1c1224, which is on a smart card), as evidence:
$ gpg --list-secret-keys

gpg: used in a production environment or with production keys!

But, when I go to sign a file (or email, or anything) I get:
$ gpg --sign test.txt
gpg: NOTE: THIS IS A DEVELOPMENT VERSION!
gpg: It is only intended for test purposes and should NOT be
gpg: used in a production environment or with production keys!
gpg: secret key parts are not available
gpg: no default secret key: general error
gpg: signing failed: general error

What could be causing this?

Thanks

Bad - You get pulled over for doing 90 in a school zone and you're drunk
off your ass again at three in the afternoon.
Worse - The cop is drunk too, and he's a mean drunk.
FUCK! - A mean drunk that's actually a swarm of semi-sentient
flesh-eating beetles.
