Null check needed in

	case PropertyNotify:
	    if (event->xproperty.atom == decorSwitchWindowAtom)
	    {
		CompWindow    *w = screen->findWindow (event->xproperty.window);

                DECOR_WINDOW (w);

		if (dw->isSwitcher && !event->xproperty.state == PropertyDelete)
		    dw->updateSwitcher ();
	    }

Just a mental note for when I wake up
