[orca-list] Why working some document with Acroread accessibility, and why not working another documents?

[Hammer Attila <hammera pickup hu>]

Dear List,

I have got a question only before I open a bugreport with Orca/Acroread 
accessibility if this is need:
I would like help an user, with tells me some time impossible using 
Acroread with document reading and reading the opened document with Orca.
Some documents working right the navigation and possible browsing the 
document, but some document is not, and only help if he save as the 
original PDF document with text file in Acroread or use pdftotext 
commandline application with this problematic documents.

I found both two example document with possible test:
1. Following document is wonderful possible read with Acroread and Orca 
if the proper accessibility related settings is setted in Acroread with 
32 bit platform:
http://fullcircle.hu/pdf/issue35_hu.pdf

2. The second attached document is impossible to navigate, and I only 
working method to save as the document with txt file and read the 
document with Gedit application. Of course, pdftotext commandline 
application wonderful convert this document.
I not see with blind, what the difference with two document? Why working 
the first linked document in Acroread and Orca accessibility integration 
and why not working the second attached document? Possible the second 
pdf file is different format?

This problem is Orca or Acroread side problem?

Attila
