Hi Nathan, Hi list :)

I ran into this too, with PyQt under Nuke and Maya. 
I *think* it's a windows only bug, what os did you use?

Anyway, it took me two days to track it: it's a segfault happening when the 
slot receives an sip object argument. 
The c++ object dies at the end of the slot w/o deref the python wrapper, and 
when this wrapper gets garbage collected the segfault occurs...

I'm using a decorator on my slot too deal with this until the next version of 
qt/sip/PyQt is usable...

Hope this can save you time!
Cheers,
Dee.
