QNetworkReply segfaults if using ssl and connection is terminated unexpectedly

When connecting to a https server and the server unexpectedly closes the connection, it causes the client to segfault.

Test code is attached.  It tries to establish a connection to localhost and do a get.  To reproduce:

1. In one terminal:

sudo nc -l 443

2. In another, run the test code.

3. ctrl+c in the netcat terminal to close the connection.
