[C++ client] EXTERNAL authentication using SSL certificates doesn't work with AMQP 1.0

A C++ based client using the qpid.messaging API with AMQP 1.0 seems to be unable to connect to the broker and authenticate with the SASL EXTERNAL authentication / SSL Client Certificates. The client side log is following:

The broker log mentions that the connection is being closed because no protocol was received (max-negotiate-timeout expired):

With AMQP 0.10 it seems to work fine.
