    Fixed problem with creation of 1st barcode.
    
    A change signal is apparently being delayed until the actual widget is
    being realized as a result of the gtk_widget_show of the object editor
    notebook.  The proper fix is to use actual signal blockers rather than
    the simple "stop_signals" flag, since the flags assume callbacks are
    always called inline rather than being called asynchronously.
