Yes, I can do that. But I think it's a bug in the API if I have to rely
on a specific implementation of an API function to do something that
simple. Why isn't there a funtion like 

guint gtk_combo_box_text_num_elements()

which returns the number of the remaining elements in the list? Because
as of now it would be perfectly legal to _not_ use a GtkTreeModel to
store list entries in case the ComboBox was created with the _text_
convenience functions.
Or the API specs should say that a combo box created with the
convenience functions will always result in normal combo box with a
GtkTreeModel and thus all functions are usable.
