[gst-devel] v4l2src (harmless) warning, why?

[Kulecz, Walter (JSC-SK)[WYLE INTEG. SCI. & ENG.]]

Why do I get this warning from v4l2src when I check the current video norm?
(HelloVideo:21453): GLib-GObject-WARNING **: IA__g_object_notify: object class `GstV4l2Src' has no property named `norm'

I check and report with:
    // report previous video norm
    GstTunerNorm *ntsc=gst_tuner_get_norm(tuner);
    g_print("Previous Norm: %s\n", ntsc->label);

And the label returned is correct, "PAL" after a reboot for this card, and "NTSC" after I or some other TV application sets it.
