Received stream processing stops if the first packet from the server has only the <stream:stream /> tag

What steps will reproduce the problem?
1.
Repeatedly run the following sequence against an Openfire server using a 
localhost connection on the same machine. The problem is intermittent, 
depending on how the server responds, but the failure occurs every time the 
condition is met.

if (!empty($xmpp_password)) {
    $conn = new XMPPHP_XMPP($xmpp_server, $xmpp_port, $xmpp_user, $xmpp_password, 'xmpphp', $xmpp_resource, $printlog=true, $loglevel=XMPPHP_Log::LEVEL_VERBOSE);
    $conn->useEncryption(true);

        try {

        $conn->connect();
        $conn->processUntil('session_start');
        $conn->presence();
        $conn->message($xmpp_rcpt, $message);   
        $conn->presence($type='unavailable');
        $conn->disconnect();

    } catch(XMPPHP_Exception $e) {
        die($e->getMessage());
    }
}
2.

Run wireshark and monitor the "lo" loopback interface with the display filter 
set to "jabber". This confirms the packet relationship.

What is the expected output? What do you see instead?

The message goes through if the first response from the server includes the 
stream:features tag:

The message does not go through if the first response is only the first tag 
even though the stream:features tag follows right after.
