Installed from:    Ubuntu Packages

Recently i played a bit around with a stylesheet on my website and it happened, that konqueror crashed when viewing any page that used that stylesheet. i was wondering and found out, that it was due to a CSS-3-Namespace-Selector, if removed the page was shown, if not konqueror crashed.

This is the crash-log:
