Creating these default folders still doesn't work. After some investigation I found that's because the template we use for the path when creating the `child` `Gio.Settings` instance results in a double slash - it comes out as e.g. /org/gnome/desktop/app-folders//folders/Utilities/ . dconf does not gracefully handle this as many other things that handle paths do, it considers it a programmer error. It results in error messages like: dconf_changeset_set: assertion 'dconf_is_path (path, NULL)' failed which is slightly confusing. Anyway, we fix it by removing a slash from the template.
