--- Comment #4 from Naxdy <xna...@hydra-development.net> ---
Apparently, this affects more applications than just kscreenlocker. I've just
had kded5 crash with a very similar backtrace. It seems to me that something in
libkscreen is causing this problem. To my knowledge, this wasn't an issue in
5.27.1, so I'm marking this as a regression.
Here's the backtrace of kded5:
