gnu/packages/patches/gnome-tweaks-search-paths.patch

   1 Gnome-tweaks does not look at GSETTINGS_SCHEMA_PATH or XDG_DATA_DIRS, it
   2 assumes that schemas are installed in one global directory
   3 (GSETTINGS_SCHEMA_DIR/gsettingsschemadir).
   4
   5 Guix/GuixSD uses a different directory for every gir package and has
   6 packages pick-up files using XDG_DATA_DIRS.
