New crash information added by DrKonqi

krusader (2.7.2 "Peace of Mind") using Qt 5.15.3

- What I was doing when the application crashed:
Downloaded a deb file: aptitude download libapache2-mod-security2
Marked that file in krusader and pressed F3.
Krusader crashed every time I tried it. Ark opens the deb file without problems.
