the fatal document

Problem description:
Libreoffice freezes when trying to print or export as PDF a particular document. This document was created by copy/paste from a private part of a Web site.

Steps to reproduce:
1. Open the attached document
2. Click on the "Export as PDF" button and on Save to launch the export or print the document

Current behavior:
libreoffice freezes

Expected behavior:
Export as PDF or print

Additional information:
Discussed this on IRC with mst_ who helped me produce a gdb backtrace which I will attach and who added:
"<mst_> jeromeg: it looks like Writer wants to load a graphic from a http URL and that blocks"
"jeromeg: hmm.. "The document has moved", perhaps it is some kind of redirect loop and our http resolver is too stupid to handle it or something"

Reproduced with

LOdev 3.5.0beta2 
Ubuntu 10.04.3 x86
Linux 2.6.32-37-generic Russian UI
Comment 3 A (Andy) 2013-05-03 21:34:34 UTC
reproducible with LO (Win7 Home, 64bit)

Result: Libreoffice crashes
Comment 4 Timur 2014-12-09 13:52:38 UTC
Problem cannot be reproduced as explained with LO 4.3 and 4.4 beta on Win7 64.
Export to PDF is very slow due to the images in file, but it finishes properly.
If image links are updated or broken in Edit-Links, export is fast.

when export to PDF LibreOffice doesn't freeze, export is about 12 sec and it created good PDF without any images. 
And in document doesn't show any images and scrolling of document has many micro freezes.

So, let's close this one as WFM now
