You are right, PySide doesn't support exception translation.

You need to implement this feature on the Generator itself, I would separate 
this in two steps:

1. Do not translate anything, just catch all C++ exception and throw a Python 
2. Think about a way to specify a exception translation mechanism in the 

The step 1 will require some changes in the generator, the generator code 
isn't trivial, besides being a bit ugly due to the bad API of ApiExtractor but 
IMO you must try to hack the generator and implement this feature.
