Description

Try a longpress and then release on a label in the listview. The longpress event registers fine, the touchend crashes the app. If you add onTouchstart="labelStart" to the XML, the crash will occur on the touchstart event. The longpress event works fine. The problem can be tracked down to calls to handleControlEvents in TiUIView.m index.xml: 
<Alloy>
	<Window class="container">
		<ListView id="lv" top="0dp" defaultItemTemplate="temp1">
			<Templates>
				<ItemTemplate name="temp1">
						<Label bindId="testMsg" onLongpress="labelPressed" onTouchend="labelEnd"/>
				</ItemTemplate>
			</Templates>			
			<ListSection id="ls"/>
		</ListView>		
	</Window>
</Alloy>
index.js: 
function labelPressed(e){
	Ti.API.info('longpress event: ' + JSON.stringify(e));	
}

function labelEnd(e){
	Ti.API.info('touchend event: ' + JSON.stringify(e));		
}

function labelStart(e){
	Ti.API.info('touchstart: ' + JSON.stringify(e));
}

var data = [];
for (var i=0; i < 10; i++) {
	data.push({testMsg: {text: 'Longpress and release - iOS crash on touchend'}});
}

$.ls.setItems(data);
$.index.open();
