QHttpNetworkConnectionPrivate::createAuthorization() in qhttpnetworkconnection.cpp sets header with lower case "a" in "authorization"

QHttpNetworkConnectionPrivate::createAuthorization() in qhttpnetworkconnection.cpp sets header with lower case "a" in "authorization". Is there any way this text could be "Authorization" with a capital 'A' instead? Logging into our devices over HTTP using QtWebKit fails authorization because the device excepts "Authorization". Yes the developers should have used a case insensitive compare, but we have dozens of devices and years of deployment of these devices.
