[Stackless] [PySide] PySide violates Python API - PyQt does not!

[Christian Tismer]

Hi John,

I tried stackless pyside on OS X after patching pyside-setup's shiboken 
a bit.

Unfortunately, the situation is still the same.
Segfault 11, then malloc_error trap 6, ...
then it suddenly runs smoothly!

It seems to be a different problem, related to initialization issues.
This needs further investigation :-(

cheers - chris
