Describe the bug

I'm using NixOS 24.11 with AwesomeWM, XScreenSaver and xss-lock. I've had this setup on all my previous distributions. I use caffeine-ng to keep the screensaver from activating when watching videos or playing games.

Using the stable version of awesome, xscreensaver, xss-lock and caffeine-ng, caffeine will segfault after some time.

Doesn't matter if xscreensaver and xss-lock are defined as services or just installed as system packages and invoked by the user on session startup. caffeine will always segfault after some random period of time.

I tried with kernels 6.11 and 6.12 - didn't affect behavior.

Steps To Reproduce

Steps to reproduce the behavior:

1. Install caffeine-ng, xscreensaver, xss-lock and use them
2. Wait for caffeine to segfault
3. ...

Expected behavior

caffeine remains running forever
