        * gtk/gtkfilechooserembed.c
        (_gtk_file_chooser_embed_get_default_size):  Add g_return_if_fail()
        (_gtk_file_chooser_embed_get_resizable_hints): Add g_return_if_fail()

        * gtk/gtkfilechooserdialog.c
        (file_chooser_widget_default_size_changed): Get the correct
        initial size for the dialog.  Also, don't bother with
        gtk_window_set_default_size().  It's not really meaningful.

        * gtk/gtkfilechooserdefault.c
        (gtk_file_chooser_default_get_default_size): Get the correct
        spacing for the preview_widget
        (update_preview_widget_visibility): Clear widget field after we
        destroy it.
