New crash information added by DrKonqi

plasmashell (5.19.5) using Qt 5.15.1

I also encountered this bug (or so it seems).

- What I was doing when the application crashed:

I was trying to connect to a wireless network using the NetworkManager Plasma widget in the panel. Plasma crashed after clicking the "Connect" button, before entering the passphrase.

-- Backtrace (Reduced):

Comment 7 David Edmundson 2021-02-25 22:23:52 UTC
We don't use that component anymore.

There's a million dupes on kdeclarative if we want to find it, with our plasma hats we can consider this fixed
