Application: okular (0.25.0)
KDE Platform Version: 4.14.22
Qt Version: 4.8.7
Operating System: Linux 4.8.0-53-generic x86_64
Distribution: Linux Mint 18.2 Sonya

-- Information about the crash:
- What I was doing when the application crashed: I opened a pdf file and scrolled the document down. Then Okular crashed. It happened twice in sequence. But I cannot identify potential causes. To me there was nothing special event correlated with the bug at the time.

-- Backtrace:
Application: Okular (okular), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
