It works just great, this is what I have :

public class FolderView : Fm.FolderView, BaseView {

        public FolderView (Gtk.Notebook parent, string directory) {

            // Object (); // not needed :)
            base.set_mode (Fm.FolderViewMode.LIST_VIEW);
            base.small_icon_size =  16;
            base.big_icon_size =    36;
            base.single_click =     false;
        }
}

I first tried to call Object () but you are absolutely correct,
just setting the properties works as expected. Marvelous. :-P

So, here's the result.

Great information, thanks a lot, I'm not very familiar with GObject yet 
and I often have that kind of troubles with derived classes.

Thank you, best regards.
