    Get the good notebook with tab to a new window
    
    error encountered :
    
    assertion 'gtk_widget_get_parent (widget) == GTK_WIDGET (container)
    ...' failed
    
    When moving tab to a new window and having several notebooks,
    make sure the source notebook is the good one
    ( wich is not always the active one )
