Description wilson_tyler57 2020-02-13 21:18:28 UTC

Application: plasmashell (5.17.5)

Qt Version: 5.13.2
Frameworks Version: 5.66.0
Operating System: Linux 5.4.18-200.fc31.x86_64 x86_64
Distribution: Fedora 31 (Thirty One)

-- Information about the crash:
- What I was doing when the application crashed:

I had just logged in from a reboot, after the behavior below i attempted to add the network widget to my desktop so i could at least connect to the network, and as soon as i attempted to turn on wifi plasma crashed.

- Unusual behavior I noticed:

I had just logged in after a reboot (initial login) and i noticed my background was the default fedora 31 background instead of my personalized one. I also noticed my panel on the bottom was not there (no task manager, system tray, etc.) and it was just a blank desktop otherwise outside of my shortcuts to an application and document i have on there.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

This should be fixed in Plasma 5.20+. The offending Plotter class is no longer used.
