No, it shouldn't do. A QAbstractItemModel is a QObject. It takes another 
QObject as its parent, not a QModelIndex:

 >>> from PyQt4 import QtCore, QtGui
 >>> app = QtGui.QApplication([])
 >>> model = QtGui.QStandardItemModel(app)
 >>> model.parent()
<PyQt4.QtGui.QApplication object at 0x7f397aae0c18>
 >>> model.parent(QtCore.QModelIndex())
<PyQt4.QtCore.QModelIndex object at 0x7f3975078358>

QAbstractItemModel::parent(QModelIndex) is virtual, but 
QObject::parent() isn't, so it cannot not be overridden.
