Bug ID: 383617
Summary: Pulseaudio causes Plasma to crash
Product: plasmashell
Version: 5.10.4
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: cchee...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.10.4)
Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.12.6-1-ARCH x86_64
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
Plug headphones in and remove them.
- Unusual behavior I noticed:
Fairly often, my system speakers stop outputting sound. I can fix that by
plugging in my headphones. Sound plays through the headphones. When I unplug
the headphones, I get the crash and when it restarts, the system speakers start
working again.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
