DBus issues when trying to scan

[TarunGunampalli]

When trying to run the sample code given, it is printing an empty array and an error:
org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1
org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1
[]

from bluetool import Bluetooth

bluetooth = Bluetooth()
bluetooth.scan()
devices = bluetooth.get_paired_devices()
print(devices)`

There are two of the dbus errors for some reason, and I assumed that they are the reason that the array ends up empty instead of having the devices. Other Bluetooth class methods also return empty lists, although I haven't tried all of them.
