Thank to everyone who contributed.

I received a private mesage from davehorner suggesting that SetXOverlay might be the problem. Right on the nose Mr Horner, I checked 3.0.0, the nearly lastest version, against 2.8.11, the version I am using, and there are some threadsafe stabity enahcements. I applied these to my version and recomplied. Voila, everything in the garden is lovely.

For anyone who has the same problem, here is the fixed code: 

//--------------------------------------------------------------------
+---------
// wxGStreamerMediaBackend::SetupXOverlay
//
// Attempts to set the XWindow id of our GstXOverlay to tell it which
// window to play video in.
//--------------------------------------------------------------------
+---------
void wxGStreamerMediaBackend::SetupXOverlay()
{
    // Use the xoverlay extension to tell gstreamer to play in our win
+dow
#ifdef __WXGTK__
    if (!gtk_widget_get_realized(m_ctrl->m_wxwindow))
    {
        // Not realized yet - set to connect at realization time
        g_signal_connect (m_ctrl->m_wxwindow,
                          "realize",
                          G_CALLBACK (gtk_window_realize_callback),
                          this);
    }
    else
    {
        gdk_flush();

        GdkWindow* window = gtk_widget_get_window(m_ctrl->m_wxwindow);
        wxASSERT(window);
#endif
        gst_x_overlay_set_xwindow_id(GST_X_OVERLAY(m_xoverlay),
#ifdef __WXGTK__
                        GDK_WINDOW_XID(window)
#else
                        ctrl->GetHandle()
#endif
                                  );
#ifdef __WXGTK__
    g_signal_connect (m_ctrl->m_wxwindow,
                        // m_ctrl->m_wxwindow/*m_ctrl->m_widget*/,
                      "expose_event",
                      G_CALLBACK(gtk_window_expose_callback), this);
    } // end if GtkPizza realized
#endif
}
