P1: Critical Description
I have a project that involves QWebView and a lot of https request.
Application crashes on both platforms: Mac 10.6 and Windows XP.

Call stack on Mac OS is pretty much the same.
It looks that the 'reply' is null and crashes here in QHttpNetworkConnectionChannel::_q_error(QAbstractSocket::SocketError socketError):
... } else if (state == QHttpNetworkConnectionChannel::ReadingState) { if (!reply->d_func()->expectContent()) { // No content expected, this is a valid way to have the connection closed by the server return; } ...
Unfortunately I don't have sample code to reproduce this.
