I'd say it's a bug in tree view sizing in GTK3.

Actually, the list is correctly updated, but the view only request space
for the initial data, and not for the newly added.  And since in your
case you don't pack it in a ScrolledWindow, the view should grow its
size request.

You can see what really happens by making your tree view expand
(gtk_box_pack_start(GTK_BOX(box), tree, TRUE, TRUE, 0) instead of
container_add(box, tree)): you will see that if you resize the window
manually you see the "missing" rows.
