Bug ID: 417600
Summary: Blank desktop on initial login
Product: plasmashell
Version: 5.17.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: wilson_tyle...@yahoo.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
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".
