New crash information added by DrKonqi

plasma-discover (5.10.5) using Qt 5.7.1

- What I was doing when the application crashed:

This seems to always occur when I open the application once. It will crash and then I can reopen without issue. This seems to always be the cycle, open crash, open works, open crash, open works etc...
