Summary Crash in CFNetwork visiting google.com

Reported 2011-03-08 12:04:34 PST
The crash occurs when trying to copy a CFURLResponseRef in WKURLResponseCopyCFURLResponse that is null underneath WebCore::MainResourceLoader::handleEmptyLoad. Since the load is empty, it is reasonable for the CFURLResponseRef to be null, and we should not try to copy a null CFURLResponseRef. <rdar://problem/9102016>
