When opening the attached file, okular is inactive for quite a while (and displays a grey empty area). When the document is finnaly open, scrolling or making any action hangs okular absolutely. I am also unable to open other documents with okular untill I kill the process. Reproducible: Always Steps to Reproduce: 1.open the attached document. 2. 3. Actual Results: Okular is slow. Scrolling hangs it forever. Document URL (don't think I am allowed to upload it) http://cds.cern.ch/record/1511050/files/Science-2012--1576-82.pdf

Works fine here in 0.19.2 for Ubuntu, can you try updating and see if it works for you?
