I would suggest a different approach: add your own column to the GtkListStore which stores your information summary as a GObject (so you know when that object is destroyed). If you can't add a column to the GtkListStore, then I suggest creating another GtkTreeModel implementation which "proxies" the GtkListStore and adds a new column (in this case you'll have to write a method to delete data so you'll know when it's deleted) - see the GtkTreeModelFilter implementation for example.
