-- Information about the crash:
- What I was doing when the application crashed:
sudo systemctl restart NetworkManager.service

I just pressed enter and it crashed. It seems like it's related to the network manager plasmoid...

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
