Bug ID: 461643
Summary: plasmashell crashes randomly when clicking in taskbar
Classification: Plasma
Product: plasmashell
Version: 5.26.3
Platform: Archlinux
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: stephanos.matsum...@sporic.me
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Application: plasmashell (5.26.3)
Qt Version: 5.15.7
Frameworks Version: 5.99.0
Operating System: Linux 6.0.7-arch1-1 x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.26.3 [KCrashBackend]
-- Information about the crash:
Only occasionally (usually once/twice per session), plasmashell crashes and
then restarts when I click in the taskbar. Sometimes this is when I click in
the task switcher, but sometimes I only need to click on another part of the
bar. I use i3 as my window manager, but occasionally I also receive a
notification that KWin has crashed.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
