if I may guess, it's because otherwise you'd have to unref the returned
widget, which would be a bit odd in the gtk+ context. it also happens in
the ::get_filter() method of GtkFileChooser (and GtkRecentChooser), for
the same reason: the implementation owns the filter and it's just
returning a pointer to it.

when you call gtk_tree_view_get_model() you don't unref the returned
GtkTreeModel because the tree view widget holds a reference on the model
itself, as it happens in this case:

yep.

it's like returning a private string as a const-gchar*. in these cases
work because it has been documented and it's more or less consistent
with the rest of the gtk+ API.
