--- Comment #4 from Øystein Steffensen-Alværvik <yst...@posteo.net> --- Here's a backtrace with gdb set to G_DEBUG=fatal-criticals. I hope I did it right. I know you requested it in https://bugs.kde.org/show_bug.cgi?id=397144 but since Discover with snap backend freezes upon launch, I can't reproduce bug 397144 (but they're probably the same, as you say).
