Yes, this is true, and I tried this.
Unfortunately, PySide does not build with Stackless Python, due to
the different definition of PyHeapTypeObject.

I saw thar PyQT had a similar problem, and it has a small patch.

PySide is different in that it requires to access to

     PyTypeObject ht_type;

which is absent in stackless.

Now I'm undecided whether to change shiboken or stackless.?
Maybe I will patch shiboken for the moment, to see if it solves the problem.

Thanks for motivating me - chris
