Ok so I've stopped trying to do the weird and wacky custom hand
written Python C Extension and gone for the pure Shiboken generated
module, as you guys suggested, which is much much nicer indeed.
However I'm still seeing the same crash, although I think I might have
narrowed it down further. It looks like it's failing when trying to
produce a python wrapper for a C++ QWidget which is actually a C++
subclass of QWidget i.e: My module works fine and produces the correct
results for pointers to 'raw' QWidget / QMenu / QCheckBox etc
instances.
So, I have a small repeatable test case, however its currently
dependent on Maya 2012. I don't suppose you guys would have access to
a copy to test my example on?
Thanks a million again for the help!
Cheers,
Daniel
