[PyQt] PyQt/QtWebKit authenticationRequired QAuthenticator TypeError

[Dan Hopkins]

Hi,
Apologies in advance if my query is ill informed, I'm new to PyQt and 
QtWebKit.

I'm testing a setup compiled from source: 
PyQt_gpl-5.7.1/sip-4.19/Qt-5.7.1/QtWebKit (from 
https://github.com/annulen/webkit/ stable branch) on Ubuntu 14.04 with 
Python2.7

I've got code that works fine with old distro packaged versions of PyQt 
et al, but I'm trying with this setup for a more recent webkit 
implementation.

The previously working code is now failing with what appears to be a 
type/pointer mismatch:

QObject::connect: Incompatible sender/receiver arguments
   NetworkAccessManager::authenticationRequired(QNetworkReply*,
                                                QAuthenticator*) -->
   WebKit::handle_auth(QNetworkReply*,QAuthenticator)
   ...
(TypeError('connect() failed between 
authenticationRequired(QNetworkReply*,QAuthenticator*) and 
handle_auth()',),)

Handler defined as:

     @Slot(QNetworkReply, QAuthenticator)
     def handle_auth(self, qreply, qauthenticator):
     ...

Is this an obvious failure to the more seasoned users out there?
Any suggestions to things I may have done to cause this, or other 
pointers just to successful builds of PyQt against Annulen's QtWebKit 
fork gratefully received.

Thanks,
Dan
