In his "Rapid GUI Programming with Python and Qt" Mark 
Summerfield gives a summary of the following formats for 
SIGNAL -  SLOT connection formats (p129):

connect(w, SIGNAL('signalSignature'), functionName)
connect(w, SIGNAL('signalSignature'), instance.methodName)
connect(w, SIGNAL('signalSignature'), instace,
                           SLOT('slotSignature)

From this I concluded, rightly or wrongly,  that the SIGNAL
format is the same in the old and the new style and only 
the SLOT syntax has changed.  So perhaps you should 
look at the SLOT part of the statement?
