Version:            (using KDE KDE 3.5.2)
Installed from:    Gentoo Packages
Compiler:          gcc version 4.0.3 (Gentoo 4.0.3, pie-8.7.8) 
OS:                Linux

I can't reproduce it very reliably, but it works about 30% of the time for me.

My home page is set to "http://www.google.com/ig?hl=en" (the customized Google page). If I open a new instance of Konqueror, and open the DOM tree viewer before it loaded the page, it often crashes:

It seems to happen only with a new instance - not when refreshing or going to a different site.
