> Hi Eric, Browser crashed on loading www.crave.cnet.com. During debug we have found out that without checking whether renderer of the element existed, it tried to find the layer and as a result the crash happened. With this NULL check we were able to prevent the crash.

Did you try to create reduction? Some simple html that crashes webkit.
If you get reduction it would be very easy to add layout test. There is a lot of tests that pass if webkit doesn’t crash.

Does it crash with frame flattening switched on?
