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

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.
