/**
* FIXME: Bug 820274
*
* If the user turns off Bluetooth in the middle of pairing process, the
* callback function GetObjectPathCallback (see the third argument of the
* function call above) may still be called while enabling next time by
* dbus daemon. To prevent this from happening, added a flag to distinguish
* if Bluetooth has been turned off. Nevertheless, we need a check if there
* is a better solution.
*
* Please see Bug 818696 for more information.
