Research direction

Start with tornado/websocket.py at _accept_connection and tornado/httputil.py at get_ssl_certificate, then trace how the WebSocket request's connection stream is initialized. Reproduce the reported WebSocketHandler call, but first clarify the expected certificate behavior because the issue does not specify what should happen instead of the traceback.
