Can I please ask you developers:
What would the best approach to fixing this be? - Upon loading the configuration, automatically remove a *null *style if the file (pophatch.xml) cannot be found/read - perhaps with a warning in a log file? - Give the user an explicit error message when rendering the UI and a *null *style is found?
