VNC client does not exits after logout

[Shin-myoung-serp]

I have setup the remote desktop using the "[VNCServer]" configuration section.
When I log in using a VNC client and log out with the desktop panel menu,
the VNC client(remmina) does not exits.

I found that a VNC connection(TCP 5900) remains alive even though the Xvnc server exits.
I also found the cause, GSocket instance is leaking in the "src/vnc-server.c".

static gboolean
read_cb (GSocket *socket, GIOCondition condition, VNCServer *server)
{
    ...
    client_socket = g_socket_accept (socket, NULL, &error);
    ...
    if (client_socket)
    {
        ...
        g_signal_emit (server, signals[NEW_CONNECTION], 0, client_socket);
    }
    return TRUE;
}

I think that "g_object_unref(client_socket)" should be called after g_signal_emit().

Was fixed in lightdm 1.25.1

Ubuntu 17.10 (Artful Aardvark) has reached end of life, so this bug will not be fixed for that specific release.
