Steps to reproduce: 1) Go to a valid site (e.g., http://www.apple.com) 2) Enter a fake domain in the url bar (e.g., http://www.apple.comz) 3) The dns error page never loads This appears related to the recent change in WebCore/loader/FrameLoader.cpp:mainReceivedCompletedError from using checkLoadComplete to checkCompleted. In the case of a failed load, m_isComplete never gets set to false so the call to checkCompleted exits early rather than making it to checkLoadComplete.
