When looking at bug #1421249 I noticed system settings did not always properly show the bluetooth state. For example, yesterday I disabled bluetooth at some point in the evening and later I went to sleep. When I woke up, I tried to turn it on via the indicator and also system settings and it won't turn on. In the indicator, the switch moves to the green position briefly, then moves back to gray (the bluetooth indicator remains hidden and bluetooth is disabled). In system settings, the switch will stay green, but the bluetooth indicator remains hidden and bluetooth is disabled. If I leave system settings and come back, the the switch is in the off (gray) position.
