Hi ! I just looked at http://bugs.kde.org//db/83/8302.html and stripped it down to This triggers assert(executingScript == false); in KHTMLTokenizer::reset() Waldo put in. It surely is there for a reason but what's the proper fix ? reset() is being called in ~KHTMLTokenizer(). Can anyone (Waldo? Peter?) shed light on this issue ? Thanks, Harri.
