This works, but please check that you're doing the following:

 - using Qt 4.5, since this feature wasn't available before

 - you create your QNetworkProxy objects without calling setType. That is:
	QNetworkProxy proxy(QNetworkProxy::Socks5Proxy);
   otherwise, you have to call
	setCapabilities(QNetworkProxy::HostNameLookupCapabitlity)
