ADDITIONAL INFORMATION
Comment 1 Maurizio Paolini 2020-01-09 17:26:09 UTC
I can confirm this behaviour:  if a kig construction contains a PythonScript object, then kig crashes upon closing it.

As reported to me by Franco, the problem is apparently in the destructor

PythonScripter::~PythonScripter()
{
  PyErr_Clear();
  Py_Finalize();
  delete d;
}

As noted by Franco, the problem disappears upon moving the 'delete d' before the Py_Finalize() call
