Go to webkit.org, open the Inspector, select the Network panel and reload the page. Click any of the text resources in the sidebar, all you get is a bit fat grey area instead of your lovely web content.
Using the inspector on the inspector (yo dawg), shows a bunch of these in the console:
TypeError: 'undefined' is not an object (evaluating 'this._textViewer.element') inspector.js:27023
Using the r83424 nightly on SnowLeopard.

Can this be tested? Opening single resource in the panel + checking that there are no errors would be sufficient.
