Bug ID: 451115
Summary: Plasmashell frequently crashes
Product: plasmashell
Version: 5.24.2
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: m.w...@web.de
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Application: plasmashell (5.24.2)
Qt Version: 5.15.3
Frameworks Version: 5.91.0
Operating System: Linux 5.13.0-30-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.24
DrKonqi: 5.24.2 [KCrashBackend]
-- Information about the crash:
- What I was doing when the application crashed:
Working normal. It happens when external monitor is attached, but also without.
Using X11.
- Unusual behavior I noticed:
Something plasmashell crashes immediatly after restarting it, but sometimes it
takes some time before it crashes again.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
