`value` can also be a Python value and will be converted to a
:obj:`GObject.Value` using the corresponding column type (See
:obj:`Gtk.ListStore.set_column_types`\()).'

def set_value(self, treeiter, column, value):

    value = self._convert_value(column, value)
    Gtk.ListStore.set_value(self, treeiter, column, value)
