in xfwm4-settings, 'active items' list is empty whereas there are active items shown in the titlebar. When dragging masked items to the 'active items' list, it changes nothing and terminal shows a bunch of errors : (xfwm4-settings:9696): Gtk-CRITICAL **: gtk_widget_get_parent: assertion `GTK_IS_WIDGET (widget)' failed (xfwm4-settings:9696): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (xfwm4-settings:9696): Gtk-CRITICAL **: gtk_container_remove: assertion `GTK_IS_CONTAINER (container)' failed (xfwm4-settings:9696): Gtk-CRITICAL **: gtk_box_pack: assertion `GTK_IS_WIDGET (child)' failed (xfwm4-settings:9696): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed (xfwm4-settings:9696): Gtk-CRITICAL **: gtk_box_reorder_child: assertion `GTK_IS_WIDGET (child)' failed i didn't find the corresponding xfconf setting.
For the record, it works in 4.6.2, and the value is stored in /general/button_layout in xfwm4 channel.
