fast/images/support-broken-image-delegate.html has been failing on Windows since it was added in r79771. See the URL for the failure diff.
It looks like this is due to a difference in the behavior of DumpRenderTree.cpp:urlSuitableForTestResult and -[NSURL(DRTExtras) _drt_descriptionSuitableForTestResult].
...and due to the new delegate callback not being exposed in the Windows WebKit1 API.
