** Description changed:

- I'm attaching a file that makes the issue visible
+ 1) lsb_release -rd
+ Description:	Ubuntu 14.04.1 LTS
+ Release:	14.04
  
- 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.
+ 2) apt-cache policy evince
+ evince:
+   Installed: 3.10.3-0ubuntu10.1
+   Candidate: 3.10.3-0ubuntu10.1
+   Version table:
+  *** 3.10.3-0ubuntu10.1 0
+         500 http://us.archive.ubuntu.com/ubuntu/ trusty-updates/main amd64 Packages
+         100 /var/lib/dpkg/status
+      3.10.3-0ubuntu10 0

- 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.
+ 3) What is expected to happen is when one opens the following attachment, it does so near instantly:
+ https://bugs.launchpad.net/ubuntu/+source/poppler/+bug/294466/+attachment/409709/+files/05-Normalizacao.pdf
+ 
+ 4) What happens is it takes ~9 seconds to render each page. In Adobe
+ Reader 11.x and PDF viewer built into Firefox it takes less than a
+ second.
