Title:
  Rendering specific PDF is very cpu intensive

Status in poppler package in Ubuntu:
  Confirmed

Bug description:
  I'm attaching a file that makes the issue visible

  Evince takes 100% cpu, for quite a while, to draw each page. In the
  sample file there are only 3 pages, but I have similar documents with
  many more, and it becomes impractical to read them.

  I used valgrind --tool=callgrind to try to detect what functions were
  the most stressful, and libpoppler comes up no top, with functions
  such as GfxDeviceCMYKColorSpace::getRGB and
  StreamPredictor::getNextLine the most expensive ones.
