Titanium size bug

var win1 = Titanium.UI.createWindow({  
    title:'Tab 1',
    backgroundColor:'#fff'
});
var tab1 = Titanium.UI.createTab({  
    icon:'KS_nav_views.png',
    title:'Tab 1',
    window:win1
});

var view = Titanium.UI.createView();


var label = Titanium.UI.createLabel({
     text: 'Does not render',
     height: 'auto',
     width: 'auto'
});

view.add(label);

win1.add(view);

// This line makes the app exit from the simulator
var size = label.size;
