Description

Problem

Scenario: TabGroup has a Window with a backgroundGradient defined. Problem: Crashes in Android Emulator. (Works fine in iPhone simulator.) This works fine in the iPhone simulator, and when creating a stand-alone Window (not part of a TabGroup), and when applying the backgroundGradient to a View.

Test case

var win = Ti.UI.createWindow({
	title:'Gradient',
	backgroundGradient: {
		type: 'linear',
		startPoint: { x: '0%', y: '0%' },
		endPoint: { x: '0%', y: '100%' },
		colors: [ { color: 'red', offset: 0.0}, { color: 'blue', offset: 1.0 } ]
    }
});

var theTab = Ti.UI.createTab({
	title: 'Gradient',
	window: win
});

var tabGroup = Ti.UI.createTabGroup();
tabGroup.addTab(theTab);
tabGroup.setActiveTab(0);
tabGroup.open();
