** Description changed:

+ [Impact]
+ pulseaudio daemon crashes, interrupting sound output/input.
+ 
+ [Test Case]
+ Theoretical test case (crash does not happen for all users):
+ 1. Get a Bluetooth audio device capable of multiple profiles (e.g. high 
+    fidelity A2DP and the lower quality headset profiles).
+ 2. Pair it with your machine and select the device in sound settings.
+ 3. Turn the Bluetooth audio device off and on again, making sure it is 
+    set to active if not automatically so.
+ 4. Select the device in sound settings.
+ 5. Check that that pulseaudio process is still running, with a start 
+    time older than when you began this test case.
+ 
+ [Regression Potential]
+ Low. This SRU affects the pulseaudio daemon only so the worst case would 
+ be loss of sound output/input. The same patches have been released to
+ 17.10 for a month already and zero regressions of the crashes have
+ occurred worldwide since then.
+ 
+ [Other Info]
+ Debdiff patch is attached to the most prolific bug 1539209.
+ 
+ [Original Description]
+ 
  Bluetooth device keep disconnect and audio output tab is empty
