A agree that we should have a regualar error message and not a bug.  

You problem is caused because you gave an symmetric algorithm instead
of an asymmetric (public key) algorithm.  Use RSA, ELG or DSA.

No.  As almost every public key system, OpenPGP uses a hubrid scheme:
a random session key is used to encrypt the message using a symmetric
algorithm (e.g. AES) and that random session key is send along with
the message encrypted using an asymmetric algorithm like RSA.

If you use -c, only a symmetric algorithm is used and both parties
must agree on the key (passphrase) by other means.
