Bug ID: 452660
Summary: Random Plasma crashes
Product: plasmashell
Version: 5.24.4
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: thrimbor+kdeb...@gmail.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Application: plasmashell (5.24.4)
Qt Version: 5.15.3
Frameworks Version: 5.93.0
Operating System: Linux 5.17.3-arch1-1 x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.24.4 [KCrashBackend]
-- Information about the crash:
I'm experiencing Plasma crashes, but so far couldn't narrow it down to some
specific action or situation.
Today it crashed when I clicked on the icon of an open dolphin instance in the
task bar, two days ago it crashed when I opened Firefox (which opens a lot of
windows).
These actions do not reliably reproduce the crash, and I've had crashes where I
didn't even actively do anything.
I've tried to install all debug symbols, but the debug dialog mentioned that
the symbols for /usr/bin/plasmashell are still not there. I will try to have
debuginfod ready the next time.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
