Application that crashed: konqueror
Version of the application: 4.3.60 (KDE 4.3.60 (KDE 4.4 >= 20090706))
KDE Version: 4.3.60 (KDE 4.3.60 (KDE 4.4 >= 20090706))
Qt Version: 4.5.2
Operating System: Linux 2.6.30.1 i686

What I was doing when the application crashed:
It happens quite often but still a little bit random. Just go to www.amazon.com and click on some items, and then click the "back" button, usually konqueror will crash and generate the backtrace in the report.

 -- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault
