Bug ID: 429241
Summary: Plasmashell crashes on every login
Product: plasmashell
Version: 5.20.3
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
Application: plasmashell (5.20.3)
Qt Version: 5.15.1
Frameworks Version: 5.75.0
Operating System: Linux 5.4.0-54-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.20
-- Information about the crash:
- What I was doing when the application crashed:
After upgrading the other day my taskbar disappeared. I had to remove Event
Calendar to get my taskbar back; before removing I had edited
~/.config/plasma-org.kde.plasma.desktop-appletsrc to find the applet that was
causing the problem.
I've installed 2 security updates this morning and rebooted and it is still
crashing on login. There are no other updates available at this time.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
