      Description

      QComboBox crashes when inserting a custom Python user data type:

      On Linux, qt 5.11, pyside2 latest git branch 5.11.

       

      from PySide2 import QtWidgets
      
      class Data(object):
          """
          Test class to store in userData. The _getitem_ is needed in order to
          reproduce the segmentation fault.
          """
          def _getitem_(self, item):
              raise ValueError("Failing")
      
      qapp = QtWidgets.QApplication.instance()
      if qapp is None:
          qapp = QtWidgets.QApplication([''])
      
      data1 = Data()
      
      widget = QtWidgets.QComboBox()
      widget.addItem('a', data1)
