See, you need to define two bools in the TreeStore, one for thre real
True/False state, other for the Inconsistant state (I'm copying this
from an example, the complete code is here [1]).

        treestore = gtk.TreeStore(str, gobject.TYPE_BOOLEAN,
gobject.TYPE_BOOLEAN, str, gtk.gdk.Pixbuf)

Then, when you define the column:

        # create a TreeViewColumn for the checkbox
        tvcolumn = gtk.TreeViewColumn('Active')
        cell = gtk.CellRendererToggle()
        cell.set_property('activatable', True)
        cell.connect('toggled', self.activatePlugin)
        tvcolumn.pack_start(cell, False)
        tvcolumn.add_attribute(cell, 'active', 1)
        tvcolumn.add_attribute(cell, 'inconsistent', 2)
