With device connected, Bluetooth indicator won't change into "Disabled" when pressing the wireless hot key

CID: 201307-14037

With a Bluetooth mouse connected, the Bluetooth indicator won't change into "Disabled" (grey out) when you press the wireless hot key to disable the wireless network and the Bluetooth.

From rfkill output and the mouse itself, the Bluetooth will be disabled correctly with the hotkey, it's just the indicator.
(And it works fine without device connected)

Steps:
1. Install 14.04.2 + update
2. Pair and connect a BT mouse.
3. Disable the wireless with the hotkey

Expected result:
* Bluetooth disabled, indicator shows that it's disabled

Actual result:
* Bluetooth disabled, but the indicator shows that it's still connected.
