So, the following code from qobject.sip is new in PyQt4-4.12.dev

        #if defined(SIP_PROTECTED_IS_PUBLIC)
            (sipSelfWasArg ? sipCpp->QObject::connectNotify(sig) :
sipCpp->connectNotify(sig));
        #else
            sipCpp->sipProtectVirt_connectNotify(sig);
        #endif

The compiler complains about sipProtectVirt_connectNotify, which means
SIP_PROTECTED_IS_PUBLIC is *not* defined. This is consistent with the
fact that sip is invoked without the -P option to generate kate
bindings.

Does this ring any bells?

Thanks,
