    Problem

    App stops / crashes at "semi-random" points without giving any error-message, after getting the XML object script crawls over the given XML Object and tries to create a real Object. So to speak parsing is returning an empty object and crashes.

    Tested on

    Simulator iOS 4.3

    Repro sequence
