      Description

      Starting the attached script test.py leads to this message followed by a hard crash of the python interpreter. I get the errors stating "UNRECOGNIZED: QSharedPointer" all over the place when working with classes using QSharedPointers. I think there are two parts of this issues:

      1. The templated QSharedPointer[ptest.A] leads to a strange error message and traceback making it hard to follow the actual problem.
      2. The crash itself.
