In PySide I have the following MainWindow definition:

Qt Code: 
  1. class MainWindow(QtGui.QMainWindow):
  2.     def __init__(self, parent=None):
  3.         super(MainWindow, self).__init__(parent)
  4.  
  5.         self.view  = QtGui.QListView(self)
  6.         self.model = QtGui.QStandardItemModel()
  7.         for i in range(10):
  8.             self.model.setItem(i, QtGui.QStandardItem("Item {0}".format(i)))
  9.  
  10.         self.view.setModel(self.model)
  11.         self.view.selectionModel().selectionChanged.connect(self._selectionChanged)
  12.  
  13.         self.setCentralWidget(self.view)
  14.  
  15.     def _selectionChanged(self,selected, deselected):
  16.         pass
To copy to clipboard, switch view to plain text mode 

When I try and connect the selectionChanged signal I crash python. It's the same as this SO post and the workaround suggestion of keeping the selection model around seems to work.

Qt Code: 
  1. self.viewselectionModel = self.view.selectionModel()
  2. self.viewselectionModel.selectionChanged.connect(self._selectionChanged)
To copy to clipboard, switch view to plain text mode 

But is this safe? And is this an official bug in PySide? I could not find anything in the bug report database.
