Thanks for looking, Phil. I don't think that is the case here, as the 
signal is connected to the widget's slot in the widget's __init__ 
method, after calling the parent class __init__. There are other users 
of the signal, however, but these objects don't give the exception.

It seems to be more frequently reported with newer PyQt/SIP releases. 
I'd suspect it is race condition, as it appears randomly, except in the 
reproducible case I have found.

Thanks
