For investigating crashes we need a backtrace. Please see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports for how to get one

I am unsure whether I have done this right.

I have removed 47560 identical lines to keep the file below the 4000 KB limit.

What's a bit odd is that you're the first person to report this for a released version, so far only people using master builds seemed affected
