[TIMOB-3477] iOS: createSound causing app to crash in 4.3

When you play() a sound created by createSound() with iOS SDK 4.3 it causes the app to crash. The same code works fine with iOS SDK 4.2.

Step 1: copy the example below into your app.js
Step 2: run the app using iOS 4.3
Step 3: click on the 'Play' button
Step 4: notice the app crash
Step 5: repeat the same steps with iOS 4.2 and it will play the sound without crashing

var win = Titanium.UI.createWindow({  
    title:'main win',
    backgroundColor:'#fff',
    exitOnClose:true,
    fullscreen:false
});

var btn = Titanium.UI.createButton({
    title:'Play'
});
var sound = Titanium.Media.createSound({url:'button.mp3'});
btn.addEventListener('click', function(){
    sound.play();
});

win.add(btn);
win.open();

Tested On

Ti SDK 1.6.1, iOS SDK 4.3, iOS SDK 4.2
