The root cause of this issue is found in QtNetwork QNetworkReplyImpPrivate class. The class doesn't maintain correct state for synchronous requests; synchronous requests are set to finished already at the beginning of the request. Wrong state blocks the QNetworkReply from emitting finished signal when the request actually completes. Since no signal is emitted an eventloop in ResourceHandle::loadResourceSynchronously hangs at Webkit’s side.

Webkit might need to have an additional check to see if the QNetworkReply contains any unread data before closing it. This is needed since a response can be received from a remote host before Webkit connects handlers for the QNetworkReply. QNetworkReplyHandler::finish could be suitable place to implement this.
