With the last release (20/01/20) I have quite frequent crash problems. Maybe the problem is a loaded .png; maybe it's my PC that with an AMD navi 10 graphics card gives me continuous problems. I got the dump only without being root. Starting from root I didn't crash!
From console:

PS: the data provided are few. Don't waste too much time on it because it's probably my system.
