New crash information added by DrKonqi

plasma-discover (5.11.5) using Qt 5.10.0

- What I was doing when the application crashed:

Right-clicked on updates available icon in the system tray in Latte Dock and selected view updates. Discover opened.  1 package to update. Clicked Update All. Progress bar scrolled to 100% and Discover immediately crashed. This time it did not display that there were no updates after completion. Last entries in /var/log/pacman.log:
