The center of the page and all content on http://www.bbc.co.uk/news/business-20934751 disappears right after the page loads in Webkit nightly r138892. This page works fine in shipping Safari and Chrome Canary so I think this might be Safari specific. OS X 10.8.2, Retina MBP.
Works: r138849 Fails: r138886 http://trac.webkit.org/log/trunk/?rev=138886&stop_rev=138850
