Bug#623130: This is poppler bug: https://bugs.freedesktop.org/show_bug.cgi?id=14265

[John Hughes]

Turns out the so called "pdf" isn't a pdf at all:

"I started looking at what it would take to implement javascript. The 
problem is all the javascript in this pdf does is check the viewer 
version and if > 7.0 loads the "XFA" plugin. The pdf contains a stream 
with 600KB of XML starting with "<template 
xmlns="http://www.xfa.org/schema/xfa-template/2.1/">". There is a 1500 
page specification for XFA at 
http://partners.adobe.com/public/developer/en/xml/xfa_spec_3_3.pdf 
Needless to say, at this point I gave up."
