New crash information added by DrKonqi

plasmashell (5.17.4) using Qt 5.14.0

- What I was doing when the application crashed:

Just started up. firefox-nightly starts on startup and it was restoring previous session even though I had closed firefox and a bunch of programs. That was probably because I restarted with shutdown -r now.
