Finally found a way to remove our begin() trickery in FrameQt.
        The (probably misnamed) Frame::setEncoding() function automatically
        calls Frame::receivedFirstData() which calls being on the working
        url, which has been passed to didOpenUrl(). Took me some hours
        to figure out that the missing charset logic, forced us to do hacks.
