In Aperture, a WebView might be dealloc'ed before didFinishLoading: is called.
The problem is that the client isn't properly retaining an offscreen WebView when they should be. Therefore the WebView is dealloc'ed when the last subresource finishes loading, and the client is never told that the load completes (because it doesn't!)
Aperture specific quirk patch is on its way.
