Ok, here you're using a different function (an attribute, use with
'set').

What I suggested to do was to use the "Simple Text API" which gives you
combo boxes that only contain strings. To create one of these, you
create a combo box and then you set a default model using
'comboBoxSetModelText'. The name of the latter is a bit confusing, I
admit, since it creates a ListStore, hooks it up with the ComboBox.

However, looking at the API again, the point is that you from then
onwards only use the functions in ComboBox, namely the "Simple Text
API".

So:
  combo <- comboBoxNew
  comboBoxSetModelText combo
  mapM_ (comboBoxAppendText combo) ["foo", "bar", "baz"]

Sorry about the confusion, I think it wasn't all clear in my head
either.

Cheers,
Axel.
