Yes, I am (at least in the beginning); but this behaviour does not 
depend on Glade. Glade can use both gtk_combo_box_entry_new and 
gtk_combo_box_entry_new_text, choosing the former if you don't enter a 
list of selections and the latter if you do. In the first case 
(gtk_combo_box_entry_new) there is no way to set a model for the 
combo_box_entry; by using gtk_combo_box_entry_new_text things go fine, 
and you can set a new model for the widget (of course destroying the 
original set of selections) and this is the workaround I am currently using.

I don't know, I got no gtk-CRITICAL, but entries are empty.
