Hello,

Since KDE 3.5.3 I keep getting crashes on 
http://conference2006.kde.org/organization/location.php when scrolling 
towards the end of the document.

Steps to reproduce:
1. Load http://conference2006.kde.org/organization/location.php
2. Scroll to the end of the document (or hit "End").

Valgrind delivers BTs looking like this:

==2391== Invalid read of size 4

khtml::RenderStyle::setBorderBottomStyle(khtml::EBorderStyle) 
(/leo/projekte/Fremde/kde-3.5/src/kdelibs/khtml/rendering/render_style.h:1164)
==2391==    by 0x6EA9F77:

bool) 
(/leo/projekte/Fremde/kde-3.5/src/kdelibs/khtml/rendering/render_block.cpp:1662)

or this

Can anybody reproduce?

A minimal testcase is attached. Warning! May crash your Konqueror.

I couldn't check for precedents as bko is currently dead.
