I'm using the latest continuous builds to add a contacts picker to iPhone. Using the documentation & this [lighthoust ticket][ticket] I have it working in the simulator, but it is crashing on the device no matter what contact I choose. Any ideas?

    btnContacts.addEventListener('click', function(e) {
        var values = {
            cancel: function () { },
            animated: true,
            selectedPerson: function (e) {
                var email = '';
                var phone = '';        

                if (e.person.email != undefined) {
                    var emailTypes = ['home', 'work', 'other'];
                    for (var emailIndex = 0, emailLen = emailTypes.length; emailIndex < emailLen; emailIndex++) {
                        if (e.person.email[emailTypes[emailIndex]] != undefined && e.person.email[emailTypes[emailIndex]].length > 0) {
                            email = e.person.email[emailTypes[emailIndex]][0];
                            break;
                        }                        
                    }
                }        

                tfFirstName.value = isEmptyStr(e.person.firstName) ? '' : e.person.firstName;
                tfLastName.value = isEmptyStr(e.person.lastName) ? '' : e.person.lastName;
                tfEmail.value = isEmptyStr(email) ? '' : email;
            }
        };

        Titanium.Contacts.showContacts(values);
