QItemSelectionModel crash

selmodel.py

from PySide import QtCore, QtGui

class MyWindow(QtGui.QDialog):
    def __init__(self, parent=None):
        super(MyWindow, self).__init__(parent)

        self.model = QtGui.QStringListModel(['sam', 'sally', 'jack'], self)
        self.v = QtGui.QListView()
        self.v.setModel(self.model)

        # OPTION 1:  It seems to me that this code should be sufficient
        # with-out any longer lasting python reference to the
        # QItemSelectionModel.  It crashes immediately in my PySide 1.2.2.
        #self.v.selectionModel().currentChanged.connect(self.print_sel)

        # OPTION 2:  This works in this context to hold a reference only for
        # the duration of this scope block.
        selmodel = self.v.selectionModel()
        selmodel.currentChanged.connect(self.print_sel)

        # OPTION 3:  I think in some cases I've had to hold a reference in the
        # enclosing widget parent like this to avoid a crash at window close.
        #self.selmodel = self.v.selectionModel()
        #self.selmodel.currentChanged.connect(self.print_sel)

        # END OPTIONS illustrating QItemSelectionModel issues
