I didn't notice that. Also, this makes the problem even weirder. Were does the version mismatch come from?
I would try to run "guix gc --referrers
/gnu/store/PATH-WITH-POWER-BACKLIGHT-HELPER"

I've had this problem for a month, I think? I'll try to confirm / falsify
tomorrow. FWIW, I don't see any mate stuff in my use profile.
