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. .
