Just installed Solus Plasma from the test ISO. When I install a Gnome app (gnote for example) the app won't start and throws an error like "GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop...' is not installed".
To correct this, gsettings-desktop-schemas has to be installed with eopkg.
As it would be tedious to add this dependency to every gnome app, I suggest to install by default gsettings-desktop-schemas in Solus Plasma.
I believe this wouldn't be an issue by default anymore. kde-gtk-config should now pull it in when you update from the ISO.
But perhaps it should rundep onto one of the gnome/gtk packages to ensure it always gets pulled in with the applications. Will take a look at what is most appropriate.
Looking at this, the only one that makes sense that is low down the dep chain is libgtk-3. But it only requires it for use with wayland. https://gitlab.gnome.org/search?utf8=%E2%9C%93&snippets=&scope=&search=org.gnome.desktop&project_id=665
kde-gtk-config was effectively pulled after last update. Thanks!
Now I don't think you can find only one gnome package that depends on it that would solve this: there are many when I look at other distros.
