Version: (using KDE Devel) Installed from: Compiled sources http://www.cambridge-news.co.uk/ appears to render fine during loading, then, when the loading is complete the page disappears. The javascript is buggy but this site did work in the past with KDE 3.1, so either the site has changed or this is a regression.
I can confirm the behaviour, but not the bug. Hitting the stop button while the page is still being shown seems to solve the problem. Changing the browser identification does as well, so I am guessing it's a local JavaScript bug --> site is broken.
