Application: plasmashell (5.10.4)

Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.10.0-30-generic x86_64
Distribution: KDE neon User Edition 5.10

-- Information about the crash:
I was listening to the music using bluetooth headset conected to the system.  Audio stopped working so I went to the audio applet to see what is happening. When I tried to switch audio profile of my headset the plasma crashed. It seems that the headset or computer disconected unexpectly when the audio stopped working.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
