**facepalm** I had a locally defined class that we overriding it. It was missing the slot.

I'm not too familiar with the new signal/slot mechanism, but a short
read on the docs suggests that your connect is in the wrong order. Its
usually <bound-signal>.connect(<slot>) and you've got it the other way
around.

Well the Screen object emits "finished" and I want to connect that to the main's screenFinished slot.
self.main.screenfinished is the slot, the self.finished is emitted by the screen class. If I reverse it:
self.finished.connect(self.main.screenFinished)
I still get the error.
