[TIMOB-14659] MobileWeb: Using HTTPClient to download certain images causes an untrappable error in some browsers

*Problem* When using HTTPClient to download an imagefile, I get a strange apparaently untrappable error in the Javascript console for SOME image files , and I can't see why some work and others don't. *Browsers* Chrome 27.0.1453.116 - copy.png works, panelC.png causes error Firefox 22.0 - both images work, no error Safari 6.0.5 (8536.30.1) - Both images causes error *Steps to reproduce* 1. Create New Mobile Project, select Classic->Default Project as Project template 2. Use the code below in app.js 3. Create Resources/comics and copy the two files attached into it 4. Run code (with imgfile variable set to 'comics/panelC.png') and review Javascript console - it should look like attached screenshot more or less 5. Run code (with imgfile variable set to 'comics/copy.png') and review Javascript console - it doesn't throw the error with this file. Incidentally, it's not the createImageView that is causing this - If it is removed, the error still occurs. *Test case*

var oxi = {};

var win = Ti.UI.createWindow();

var view = Ti.UI.createView({
	opacity : 1,
	backgroundColor : 'white'
});
win.add(view);
win.open();
var imgfile = 'comics/panelC.png';
var imgLoader = Ti.Network.createHTTPClient({
	onload : function(e) {
		Ti.API.info('image loaded');
		win.add(Ti.UI.createImageView({
			image : imgfile
		}));
	},
	onerror : function(e) {
		Ti.API.info('some error occured');
	}
});

imgLoader.open("GET", imgfile);
imgLoader.send();
