Description Edar José Blanco Rodríguez 2022-12-10 04:49:06 UTC 
Application: plasma-systemmonitor (5.26.4)

Qt Version: 5.15.7
Frameworks Version: 5.100.0
Operating System: Linux 6.0.10-arch2-1 x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.26.4 [KCrashBackend]

-- Information about the crash:
The app just starts crashes, it doesn't even allow you to see the graphical interface, it just starts to load the indicator and leaves us there, this started to happen from the plasma version 5.26.3 I thought it would be fixed in 5.26.4 but it hasn't been like that

The crash can be reproduced every time.

-- Backtrace:
Application: Monitor del sistema (plasma-systemmonitor), signal: Segmentation fault
