NappDrawer: App crashes after setting centerWindow multiple times (iOS)

I can’t explain why the example is working, but when I set new center windows the app crashes without any messages in the console. It just stops.

Add some timeouts after the main window has opened;

drawer.open();

setTimeout(function() {
	
	var w = Ti.UI.createWindow({
		backgroundColor: 'red'
	});
	drawer.setCenterWindow(w);
},7000);

setTimeout(function() {
	
	var w = Ti.UI.createWindow({
		backgroundColor: 'green'
	});
	drawer.setCenterWindow(w);
},9000);

setTimeout(function() {
	
	var w = Ti.UI.createWindow({
		backgroundColor: 'blue'
	});
	drawer.setCenterWindow(w);
},11000);

setTimeout(function() {
	
	var w = Ti.UI.createWindow({
		backgroundColor: 'orange'
	});
	drawer.setCenterWindow(w);
},13000);

This will crash the app after the second window (green) has been set.
