Application: plasmashell (5.10.2)

Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.11.6-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
When I am hang up on call which uses microphone plasma crashes I think due to a problem with no properly handling pulseaudio sink.

The crash can be reproduced every time.

-- Backtrace:
Application: Plazma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
