4.3 new install clipboard broken

4.3 new install.
No notification when using the global clipboard keys.
When using global settings to change to one of the others, no effect either.
When putting the paste key I get permission denied.
Ok seems the policy config is broken.
But I have no clue how the policy wngine works nowadays.
The directory structure isn’t obvious and the docs are a mess.

Edit:
Backup restore fails with permission denied.
So it seems all kinds of policy stuff is broken.

Is there a global reset for that?

I found this closed bug report (although “closed” means it was supposedly fixed) :

Nothing worthwhile in there.
Different here.
