Application: akregator (1.6.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-21-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I upgraded Ubuntu Karmic -> Lucid, and the first time akregator started, I was moving through items quickly to mark them all as read and akregator crashed suddenly.  Re-starting Akregator and going through the process again seemed to work fine.

The crash does not seem to be reproducible.

 -- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
