Version:            (using KDE KDE 3.2.0)
Installed from:    Compiled From Sources
Compiler:          gcc 3.3.2 running on a modified RedHat 6.1, kernel 2.4.22, X 4.03
OS:          Linux

As soon as the mouse comes near a link in the fixed menu on the right of http://www.w3.org/QA and on other pages that use the same style sheet, Konqueror crashes. Some pages with this style crash as soon as you open them, with the same stack trace.

I've seen this happening in KDE < 3.1, but in KDE 3.2 it seems to be back.

I'm not sure this is purely KDE's fault, because on this machine I have other strange things happening, that don't occur on another machine (with Debian unstable): Alt-Tab insisting on using CDE-style, while Alt-Shift-Tab uses KDE-style; first click not being passed to Konqueror, while it is passed to all other applications...

I tried upgrading Qt from 3.2.2 to 3.3.0, but that makes no difference.

Here is the stack trace:
