powerdevilrc file that triggers the crash

I've worked around this issue by deleting my `~/.config/powerdevilrc`. Attached is the one that caused the crash.

Thanks for the bug report. We just got to the bottom of Bug 482668 - could this one be similar, in that the Sleep action was once supported on your system but is now disabled in systemd? Or because you moved your OS drive to a different system?

Definitely not the latter. Sleep was supported at one point, but it was also something I've disabled pretty much immediately (as one of the first things) after setting up this install of Arch. More than a year and a half ago.

Okay, then that looks like the same root cause. In Plasma 5.x, config files were generated immediately when the desktop was first started. The "Sleep" power actions were probably configured that way, and the lines were not dropped because they're different than your current default (which can't be "Sleep" because that's disabled). You've already identified a workaround and the fix will be the same, so I'll mark this as a duplicate.

Your "TurnOffDisplayWhenIdle=false" setting is harmless, you can put that back if desired.
