The access manager is only one, while we can make requests from different parts of the application, so relying on the manager finished() signal to see if something was done or not was a not very good move. The QNetworkReply is created when a get() is invocked on the AccessManager and that's unique. connect it's finished() signal instead. bonus: code cleanup.
