- What I was doing when the application crashed:

I was trying to view pdf file linked from http://www.nem-tr.cz/cze/nase-oddeleni/komplementarni-oddeleni/radiodiagnostika/ - the link target is http://www.nem-tr.cz/cze/getfile.php?FileID=1002

New crash information added by DrKonqi

okular (0.20.2) on KDE Platform 4.14.2 using Qt 4.8.6

- What I was doing when the application crashed:

Surfing the net with konqueror and trying to read a pdf file makes okular to crash (segmentation fault). I don't know if the bug can be fixed since I am using debian stable jessie (yes, it should be *stable*...)
I can read the pdf just fine if I use chrome instead, so the bug is konqueror-related.
