[TIMOB-25775] iOS: Cannot get gradient properties after creation

var win = Titanium.UI.createWindow({
    backgroundColor:'#fff'
});

var gradient = {
    type: 'radial',
    startPoint: { x: 50, y: 50 },
    colors: [ 'red', 'blue'],
    startRadius: '90%',
    endRadius: 0
};
var radialGradient = Ti.UI.createView({
    width: 100,
    height: 100,
    backgroundGradient: gradient
});

win.addEventListener('open', function() {
  console.log(radialGradient.backgroundGradient.colors.join(', ')); // CRASH!
});

win.add(radialGradient);		
win.open();
