Application that crashed: konqueror
Version of the application: 4.3.00 (KDE 4.3.0)
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-ARCH i686

What I was doing when the application crashed:
I had 3 tabs open in konqueror, one at http://archlinux.org, one at http://oswatershed.org and on at http://www.kde-look.org/content/show.php/Linux+&+AntiX+Midba?content=109429

I was on this last page when Konqueror crashed. The page was loading and I realized it was not what I wanted so I clicked the back button. I cannot be sure if the page had loaded all the way but I do not think it had.

I believe a combination of the page trying to finish loading something while I clicked the back button with the left mouse button (the regular one) is what caused this crash.
