[PyQt] PyQt4 signal issue

I am observing an issue disconnecting a signal using the new style signal-
slots API. If the signal to be disconnected is not connected, I am getting a 
TypeError exception. Using the old style API, the code silently ignores the 
disconnect. The little script in the attachment shows the issue by commenting 
the various lines in the disconnect_method method. Is there a method to check, 
if a signal-slot connection has been established (e.g. 
mySignal.isConnected(slot) )?
