gtk_dialog_run() also connects to the 'response' signal. You cannot
rely on signal callbacks being called in any particular order. In your
case, likely your handler (gtk_widget_destroy()) is getting called
before gtk_dialog_run()'s response handler, so you destroy the widget
before the gtk_dialog_run() response handler can run.
