This could come from gst_ximagesink_expose(). We call this also from the event
thread (both ximagesink and xvimagesink). The expose impl look like this:

  gst_ximagesink_xwindow_update_geometry (ximagesink);
  gst_ximagesink_ximage_put (ximagesink, NULL);

where _put is handling ximagesink>xwindow == NULL.

Simmilar we could drop the assert from _update_geometry() and add this check.

  if (G_UNLIKELY (ximagesink->xwindow == NULL)) {
    g_mutex_unlock (ximagesink->flow_lock);
    return;
  }
