What I found is
1. It enter sendResponseIfNeeded()
2. It enter last if(redirection.isValid()) block, m_resourceHandle is still
valid
3. It execute "client->willSendRequest", m_resourceHandle is staill valid
before entering willSendRequest()
4. Some callback trigger QNetworkReplyHandler::abort() and reset
m_resourceHandle to Nil
5. Back to sendResponseIfNeeded(). Null pointer access when executing
newRequest.toNetworkRequest(m_resource->getInternal()->m_frame);


I do believe it is a real bug that need to be fixed.
I tried qt 4.6.0, webkit.org svn trunk at 20 Oct 2009, all experience this
problem.
