New crash information added by DrKonqi

plasmashell (5.18.1) using Qt 5.14.1

- What I was doing when the application crashed:
Disabling "Hotspot mode" via the Wifi widget.

After numerous failed attempts to connect to an access point, I decided to click the "Hotspot" button on the top of the Wifi widget. After about 15 seconds, while the hotspot connection was still "configuring the interface", I hit the button again to disable it; that's when Plasma restarted itself.

This should be fixed in Plasma 5.20+. The offending Plotter class is no longer used.
