Summary: kmix crashes plasma
Product: plasmashell
Version: 5.14.2
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: ailinca.mar...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.14.2)
Qt Version: 5.11.2
Frameworks Version: 5.51.0
Operating System: Linux 4.18.16-zen1-1-zen x86_64

-- Information about the crash:
Sound was going through the laptop and not through the USB headsets that I
have. I wanted to change the sound to the headsets so I clicked the KMix tray
applet.
Everytime I am doing this KMix crashes and sometimes plasma as well.
I am also running a KVM machine that gets the sound through pulse.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Bus error
Using host libthread_db library "/usr/lib/libthread_db.so.1".
