Hm, perhaps.  So, Andrew, could you test with:

openssl s_server -accept 4465 -debug -msg -cert /path/to/cert.pem -key /path/to/key.pem -CAfile /path/to/ca.pem

and

gnutls-serv --port 4465 --debug 4711 --x509certfile /path/to/cert.pem --x509keyfile /path/to/key.pem --x509cafile /path/to/ca.pem

Replace /path/to/*.pem with your server's certificate/key/ca files.

Thanks,
