Application: akregator (4.8.3)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.2
Operating System: Linux 3.4.2-1.fc16.x86_64 x86_64

-- Information about the crash:
- What I was doing when the application crashed:

Scrolling through an article using the trackball's scroll wheel.  Did a downscroll, overshot a lot, scrolled back up a ways, overshot a little, scrolled down a little bit, and Akregator crashed.

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