    the runner doesn't handle D-Bus disconnect properly
    
    It appears that if the connection to D-Bus is lost or some such is
    lost, HAL doesn't check the result of DBusPendingCall from
    dbus_connection_send_with_reply() [1] to see if the result is not NULL
    and as such an invalid case is being hit within the D-Bus API and
    we're hitting a D-Bus assert and causing a crash.
    
    Provided is a patch to see if it's NULL and handle it properly.
