Description Jeff Tratt 2020-11-17 14:21:39 UTC 
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

Comment 2 David Redondo 2020-11-18 11:50:38 UTC 
Something to do with a specific plugin probably
Comment 3 Jeff Tratt 2020-11-18 16:47:52 UTC 
Created attachment 133437 [details]
plasma-org.kde.plasma.desktop-appletsrc

I've attached the file that originally had 'Event Calendar' in it. I
renamed it and let the system recreate it, then copied over a couple of
things from the backup. I'd be happy to remove it and add things manually
if it will help. I'm not using event calendar at the moment, since it was
making the entire panel disappear.
