The problem is that RSAPublicKey structure is RSA specific. GnuTLS
supports the generic SubjectPublicKeyInfo structure for public keys
which may contain RSA, DSA, or ECDSA keys. If however you provide a
simple patch that reads the structure for an gnutls_pubkey_t, I'll be
happy to include it in the 3.1 release.
