Likely same or very similar bug on Ubuntu 17.04 with Intel 7260
bluetooth hardware [8087:07dc]. Disabling Bluetooth causes indicator
icon to disappear. I can make it reappear again, albeit usually in a
disabled state, by enabling Bluetooth in control centre. Then to
actually enable, I must enable via indicator as the last step.
(Alternatively switch on->off->on in Control centre, which also finally
enables Bluetooth again.)

RF-kill and device states:
0. Bluetooth enabled and indicator icon visiable (normal):
- "hcitool dev" shows 1 device
- 3: dell-bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no

 
1. After disabling Bluetooth via indicator icon (causing icon to disappear)
- "hcitool dev" shows no devices
- 3: dell-bluetooth: Bluetooth
	Soft blocked: yes
	Hard blocked: no

2. Enable Bluetooth in control centre
Most often goes to state where a device is present, but still soft blocked, and indicator icon reappears in a disabled state. Sometimes it works as expected the first time and fully enables Bluetooth radio.


This is what my system logs tell me when I disable Bluetooth:

Not too pretty, even though most complaining seems to come from Bluetooth audio integration. 

And here's when I enable:

(In the above log examples, Bluetooth enabling worked as expected. I do
not yet know what conditions are required for it to not fully enable the
first time, which is what I usually experience.)

Title:
  bluetooth indicator disappears every time bluetooth is being turned
  off

Status in indicator-bluetooth package in Ubuntu:
  Confirmed

Bug description:
  In Ubuntu 16.04, every time I turn off bluetooth, the indicator icon disappears from the top panel.
  Each time I have to re-enable it by system setting or via dash.

  I expect it to behave in a same way as network indicator instead of
  disappearing.
