Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc-3.3.4 
OS:                Linux

To reproduce go to http://www.rogavis.no At this page I middle click on the story links to open them in background tabs. On some (I think it may be if I try to open more than one background tab) ocasions Konqueror crash.

What I have been able to find is this backtrace:

And I also observed that when running top it shows one process of nspluginviewer running wild consuming >80% CPU.

Starting Konqueror from CLI gives this (partial) traceback:
