Titanium.Yahoo.yql not working on ios

Hi, I'm trying to use Yahoo yql on IOS but emulator and device crash, it is working on Android...

this is my code

var theYql = 'SELECT * from yahoo.finance.xchange WHERE pair IN (' + currencies + ')';
 
//Ti.API.info("theYql " + theYql);
 
Ti.Yahoo.yql(theYql, function(e) {
    //Ti.API.info(e.success);
    Ti.API.info(JSON.stringify(e.data));
});

I tried also the sample from Kitchen sink with the same result

any idea...? I'm on OSX 10.9.4
