No.

Add "-vvvv" to the command-line and you'll get a ton of useful output.
E.g.:

rjhansen:~ rjh$ gpg -vvvv foo.gpg
gpg: using character set `US-ASCII'
:pubkey enc packet: version 3, algo 1, keyid 97B2C95A0569E3E6
        data: [2048 bits]
gpg: public key is 0569E3E6
gpg: using subkey 0569E3E6 instead of primary key FEAF8109

You need a passphrase to unlock the secret key for
user: "Robert J. Hansen"
gpg: using subkey 0569E3E6 instead of primary key FEAF8109
2048-bit RSA key, ID 0569E3E6, created 2005-02-22 (main key ID FEAF8109)

gpg: public key encrypted data: good DEK
:encrypted data packet:
        length: 311
gpg: encrypted with 2048-bit RSA key, ID 0569E3E6, created 2005-02-22
      "Robert J. Hansen"
gpg: AES encrypted data
:compressed packet: algo=1
:literal data packet:
        mode b (62), created 1162504119, name="rand.cc",
        raw data: 472 bytes
gpg: original file name='rand.cc'
gpg: decryption okay
gpg: WARNING: message was not integrity protected




... Looks just fine to me.  :)
