I've noticed problems when connecting to old openssl servers, and
to stronghold (the one that www.amazon.com uses). There was something
in the version advertizing of gnutls that made the KX_RSA ciphersuite
to fail. If this is the case, you may use gnutls 0.3.2 that operates
differently, or define only one version to use (ie only TLS 1.0, or only
SSL 3.0).
