Bug 330157

Application: okular (0.17.5)
KDE Platform Version: 4.11.5 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.12.7-300.fc20.x86_64 x86_64
Distribution: "Fedora release 20 (Heisenbug)"

-- Information about the crash:
- What I was doing when the application crashed: I opened a pdf just downloaded from net and was trying to scroll down.

- Unusual behavior I noticed: The scrolling seemed to be pretty slow and the text and images appeared quite hazy, and then the whole application crashed within a few seconds.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
