              The file in question is malformed, on the third page there the content stream is specified by the object stream 16 0 obj which is not properly terminated. My guess is that there is an issue with the PDF encoder PDF-XChange when no content is specified for a page. The issue is pretty easy to compensate for with a few checks in the page class. I won't look to fix this at the parser level as it is an odd corner case that we've never seen before.
