Bug ID: 405659
Summary: Plasma segfault when removing widget
Product: plasmashell
Version: 5.13.5
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: ron.atk...@tekfusioninc.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.13.5)
Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.18.0-16-generic x86_64
Distribution: Ubuntu 18.10
-- Information about the crash:
- What I was doing when the application crashed:
I noticed that my weather widget was missing from the system tray. I turned it
back on in the configuration settings but it didn't show. I then add the
weather widget directly on the panel. It then occurred to me that what I
needed to do was logout and in. After a log cycle the weather came back under
the system tray so I attempted to remove the duplicate that was on the panel
directly and Plasma crashed.
- Unusual behavior I noticed: Missing both the weather widget and MS Teams
widget.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
