Application: plasmashell (5.24.4)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.15.0-43-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.04.1 LTS
DrKonqi: 5.24.4 [KCrashBackend]

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

I have set the taskbar set to be a panel on top of the screen. Sometimes kde plasma crashes after bringing widgets to the taskbar. The issue has happened  with widgets such as digital clock and color picker. 

Also  I once had Plasma crash on me when I was dragging a custom System Montior Widget that I had configured to show CPU, GPU, Memory usage + Download, Upload Rate.  The widget was working fine but once when I was moving it on the desktop plasma had a crash. 

- Custom settings of the application:

Taskbar is configured to be on top of the screen like gnome. No 3rd party widgets.

System Montior Widget was configured to show GPU, Memory, ... details in the Sensors details tab. The sensor had a display style of Horizontal Bars.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
