Excuse me, I don't understand the relation between your question and the patch below. If there is no relation, please open a new thread by clicking on "new mail" instead of "reply all". Maybe that some kind developers will help you but you'd have more chances by providing your command line and more debug details showing that you tried to debug it by yourself and you are not a lazy developer.
