Setting schema "FileChooser" is not installed on some programs

Hello,
It seems some packages has a problem with gschema not found. The packages that have this issue so far:

  • Okular kdePackages.okular
  • xca xca

It ends up like this when file menu gets triggered (File → Open…, etc):

(xca:336380): GLib-GIO-ERROR **: 10:30:02.337: Settings schema 'org.gtk.Settings.FileChooser' is not installed

In org.gtk.Settings.FileChooser’ is not installed when running i3, @jtojnar said

This means quite systemic defect or bug. I wish to investigate this but not right now. If anyone has input on how this proceed or want to add another package with this condition.

Are you on nixos atm? Usually wrapGAppsHook4 (or 3) should address this in any case.

Yes, I’m using NixOS.

Thank you I will try it and report it here.
