Bug ID: 433821
Summary: Plasmashell randomly, frequently crashes when
interacting with the panel
Product: plasmashell
Version: 5.19.5
Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: emmajanebonest...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.19.5)
Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-7642-generic x86_64
Windowing system: X11
Distribution: Pop!_OS 20.10
-- Information about the crash:
- What I was doing when the application crashed:
I often experience frequent crashes (10+ a day) of the Plasma shell when
interacting with Plasma's panel in any way except for programs that are already
pinned in the task manager. Editing/configuring the panel, adding or removing
widgets, accessing the application launcher, etc, will randomly cause a crash.
Less often, these crashes will occur when using the System Settings as well.
The application launcher most often causes a crash when typing a search term
into it. It generally restarts itself within a few moments, but the KDE Crash
Handler very rarely appears (maybe once every two weeks) to offer an easy way
to backtrace the crash. Has been occurring for months, and it is not
ameliorated even by a fresh/clean install.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
