Application that crashed: akregator
Version of the application: 1.5.1
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31-ARCH i686

What I was doing when the application crashed:
Having pressed Alt+Left during webbrowsing in akregator causes a crash sometimes. It's hapenned 4 or 5 times already. But I'm not able to reproduce the crash. Sometimes it does, sometimes it doesn't.
