No offense taken, but I'd like to point out that I did read the  
documentation, and it is rather vague. It says:

Sets iter to the currently selected node if selection is set to  
GTK_SELECTION_SINGLE or GTK_SELECTION_BROWSE. iter may be NULL if you  
just want to test if selection has any selected nodes. model is filled  
with the current model as a convenience. This function will not work  
if you use selection is GTK_SELECTION_MULTIPLE.

It hadn't occured to me that "model is filled with the current model  
as a convenience." meant it is not necessary

Cheers
