commit 90607b28d21fefc43657ca08b889bdb174c31fab
Author: David Faure <faure@kde.org>
Date: Wed Sep 28 17:26:47 2011 +0200

Use HTML escaping on texts that come from the website
    
    Interestingly enough, this is yet another use case for moving Qt::escape
    to QtCore, which I made a merge request for.
    (cherry picked from commit 86622e4db182f4b914169f72ebd1e66d708e9f87)
