You still haven't installed debuginfod so the backtrace is as bad as every time you post it.

The instructions aren't clear. OK so apparently I had to logout after installing debuginfod or just give gdb an environment variable, I'll update the attachment in a few moments.

Do you have multiple screens? Or anything in your screen situation that you think it's "unusual?
(In reply to Albert Astals Cid from comment #9) > Do you have multiple screens? Or anything in your screen situation that you > think it's "unusual? Yes, I have a 1920x1080 HDMI monitor and two identical 1680x1050 (16:10) DVI monitors, one of which is connected with an adapter to DP because I don't have another DVI port on my graphics card.
ok, should hopefully be fixed with https://invent.kde.org/network/krdc/commit/fdec6d33003230bfca0c08e148f7253709f246cf If you update to 22.08.1 and still have this crash please reopen this issue
