Yes, good point. No doubt it's something to take into account.

But as he says "the first entry in the gtk_tree_view", I supposed the
tree view will be sorted only before to enter all data, with the
"special" entry as first.

What the example I posted does is to maintain the first entry - in the
model - always as first, despite of the tree view being sorted ascending
or descending.
