+            Reviewed by Dean Jackson.
+
+            * platform/URL.cpp:
+            (WebCore::URL::URL): Work around bug that causes this assertion to fire on
+            the Apple Windows build.
+            * platform/network/cf/SynchronousResourceHandleCFURLConnectionDelegate.cpp:
+            (WebCore::adjustMIMETypeIfNecessary): Added. If the URL is for a local file,
+            determine the MIME type based on extension. Otherwise use the default MIME type.
+            (WebCore::SynchronousResourceHandleCFURLConnectionDelegate::didReceiveResponse): If
+            the CFURLResponse has no MIME type, call 'adjustMIMETypeIfNecessary'.
