Well, there's always gpg --list-packets --with-colons, which outputs
something like:

:pubkey enc packet: version 3, algo 1, keyid 08D014DED0B337AA
        data: [4095 bits]
:pubkey enc packet: version 3, algo 16, keyid 921EB6497074473C
        data: [1024 bits]
        data: [1021 bits]
:encrypted data packet:
        length: 69
        mdc_method: 2
:compressed packet: algo=2
:literal data packet:
        mode b (62), created 1305194688, name="foo.txt",
        raw data: 4 bytes

...so just look for the "pubkey enc packet" lines, get the key IDs and
possibly pass them through another round of "gpg --list-keys --with-colons"
or something.

G'luck,
Peter
