 /**
  * Some rules for dealing with memory in DBus:
  * - A DBusError only needs to be deleted if it's been set, not just
  *   initialized. This is why LOG_AND_FREE... is called only when an error is
  *   set, and the macro cleans up the error itself.
  * - A DBusMessage needs to be unrefed when it is newed explicitly. DBusMessages
  *   from signals do not need to be unrefed, as they will be cleaned by DBus
  *   after DBUS_HANDLER_RESULT_HANDLED is returned from the filter.

      * If the user turns off Bluetooth in the middle of pairing process,
      * the callback function GetObjectPathCallback may still be called
      * while enabling next time by dbus daemon. To prevent this from
