Application: kile (2.1.0)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Using arrow keys to scroll down. Restarted kile after crash from pasting. Scrolled about three lines before crash.
- Unusual behavior I noticed:
Okular was displaying pdf of LaTeX file open in kile. Okular was line-scrolling without any user input to do so. Paged-up but okular continued to scroll.

-- Backtrace:
Application: Kile (kile), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
