Thanks for the direction Phil. I added sip.setdestroyonexit(False) to__init__ in my MainWindow class and that appears to have negated the crashing on the two apps I tried it on. Simply commenting that command out again caused the same apps to crash after adding it. So it's definitely the right direction.
My limited knowledge of sip, do I risk any memory leaks or other unexpected behavior by bypassing the c++ destructor call this way? Are there any cleanup methods/calls I should add when setting setdestroyonexit to False?
