Bug ID: 383098
Summary: Plasma crash on audio volume change
Product: plasmashell
Version: 5.10.4
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: 0talal.ma...@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 4.10.5-galliumos-braswell x86_64
Distribution: Ubuntu 16.04.3 LTS
-- Information about the crash:
- What I was doing when the application crashed:
Running audacity and recording from microphone.
Running USB DAC via ALSA instead of pulseaudio, not sure sure if that is the
cause.
The crash does not seem to be reproducible.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
