I get the same SEGV when I disconnect my laptop from my ThinkPad dock (with screens/keyboard/mouse) and immediately close the lid which triggers swaylock. On wake-up, I find my laptop unlocked.

Also happens to me regularly. I am using the latest stable version installed from fedora modules rolling. This issue is quite annoying because I cannot assume the my notebook is securely locked.
