I also always did it the way Walter described. Until I recently found 
out that if you enter something as an item in Glade (one character is 
enough), and then remove it again so you keep an empty combobox. Then 
this piece of code is enough:

for item in ["foo", "bar"]:
    combobox.get_model().append([item])

Apparently after entering something in Glade, the liststore etc are 
generated. And by removing these items, it keeps these.
