FWIW in case anyone ever ends up doing stuff with the qgtkstyle (or
gtk directly for that matter), you want to save and restore the error
handlers such that the gdk handler does not remain set.

like so:
   x11ErrorHandler qt_x_errhandler = XSetErrorHandler(0);
   QGtkStylePrivate::gtk_init (NULL, NULL);
   XSetErrorHandler(qt_x_errhandler);
