Safari blank page from Umbraco-driven site

I am running a site using Umbraco 4.

In Safari (Mac) when I refresh the page I get a completely blank page; the page appears to have finished trying to load.

I'm using a lot of JavaScript so I tried to removing all JavaScript but开发者_JAVA百科 the error still persists.

The site is here

http://www.dreamguts.com/

I would really appreciate any input.

I have done some digging on this and it would appear to be a bug in Webkit:

The bug report suggests that disabling the WebCore cache via Debug menu may help.
