Missing plasma5-kde-gtk-config somewhere causing warning Failed to load module "colorreload-gtk-module" in some GTK apps

The xdot executable installed by x11/py-xdot always prints this when it 
starts:

Gtk-Message: 11:36:38.401: Failed to load module "colorreload-gtk-module"


Based on this answer 
https://unix.stackexchange.com/questions/612098/failed-to-load-module-colorreload-gtk-module/629998#629998 
installing plasma5-kde-gtk-config helps, the warning is gone with it.


But I don't know where this dependency is missing. Maybe somebody would 
know and would be able to fix this minor annoyance.



Thanks,

Yuri
