SegFault on a GtkTreeSelection changed : More info

[Nicolas Soubeiran <nicolas soubeiran gmail com>]

I forgot to precise : I am working on a GTK+ 2.12.12 version.

I attached for debugging "row-deleted" to models signal and I saw that the
order is
1) Child model (the GtkListStore) : "row-deleted"
2) GtkTreeViewSelection (that display the sorted model) "changed"
3) GtkTreeModelSort : "row-deleted"

So it appears that the GtkTreeSelection listen to the GtkListStore changes
and received them before its model (the GtkTreeModelSort).
So the GtkTreeViewSelectionForeach is called on a model that is not up to
date.
So my question is why the GtkTreeSelection does not only listen its model
changes?
Thanks
