In GTK dispose can be called before the last ref is reached. This happens when you close the container window. The dispose will be explicitly called, and destroyed notify will be fired. This patch fixes this race by properly tracking the widget state. In the sink, we now set the widget pointer to NULL, so the widget will properly get created again if you set your pipeline to NULL state after the widget was destroy, and set it back to PLAYING. https://bugzilla.gnome.org/show_bug.cgi?id=751104
