[poppler] Found PDF which causes hangs

[Albert Astals Cid]

Nah, it's not hanged, it is just extremely slow. Anyway poppler from trunk (or 0.17.1) should just be fine with it. Can you please give it a go? (i'm with internet access only at the moment can not try myself)

I found a page in a PDF causes Poppler to get stuck in an infinate loop while rendering.The same PDF renders fine in Acrobat, Apple Preview and Google Chrome - while Poppler just hangs.
 The PDF can be downloaded from: http://midnight-labs.org/temp/hangs-poppler.pdf (2.5mb) 
This was extracted using pdftk (iText), the pages either side of it rendered fine.
I've tested against todays git checkout and a ~1 month old snapshot of Poppler on Linux, and Poppler 0.16.6 (from MacPorts) on Mac.

The common backtrace I've found, even after 20+ minutes of running is:  #12 0x0808958c in Gfx::display ()  #13 0x0808c777 in Gfx::doForm1 ()  #14 0x0808d5bd in Gfx::doTilingPatternFill ()
  #15 0x080919bd in Gfx::doPatternFill ()  #16 0x08092128 in Gfx::opFill ()  #17 0x08089158 in Gfx::go ()  #18 0x0808958c in Gfx::display ()  #19 0x080c65b5 in Page::displaySlice ()

I'll file a BugZilla report later today when I've had a better look at it, and I'm happy for the PDF to be used for regression testing etc.
