Here is what I do to dynamically populate a combobox:

presetTemplateCombobox = self.wTree.get_widget("presetTemplateCombobox")
listStore = gtk.ListStore(gobject.TYPE_STRING)
presetTemplateCombobox.set_model(listStore)
cell = gtk.CellRendererText()
presetTemplateCombobox.pack_start(cell, True)
#presetTemplateCombobox.add_attribute(cell, 'text', 0)
presetTemplateCombobox.append_text("blablabla")
...

Note that if I use the add_attribute() method, I get the entries twice on 
each line... Don't know why.
