Subject Re: java.lang.IllegalArgumentException: Only non-null Positions with an index can be checked

Hi Gregory,

I cannot reproduce the exception with that material.
Can you describe your environment (comprising jar coming with FOP) ?
What FOP SVN revision do you use?
When invoking FOP feeded with an XSL-FO, is there a file location in the
  if yes, that should help to retreive the faulty formatting object, if any

And so on. And then I'd replace all text with dummy text. If that was all successfull, I'd
have a short fo file without images or copyrighted text. I'd even try to remove as many attributes
as possible. And that's what Vincent wants.
