I've been looking through the code for this and am adding some notes here in case they help anyone else (or me to recall later).
As Jordan observes, these errors are telling us about the problem: (users-admin:724): Gtk-CRITICAL **: gtk_tree_sortable_get_sort_column_id: assertion `GTK_IS_TREE_SORTABLE (sortable)' failed (users-admin:724): GLib-GObject-WARNING **: invalid cast from `GtkTreeModelFilter' to `GtkTreeSortable' (users-admin:724): Gtk-CRITICAL **: gtk_tree_sortable_has_default_sort_func: assertion `GTK_IS_TREE_SORTABLE (sortable)' failed (users-admin:724): GLib-GObject-WARNING **: invalid cast from `GtkTreeModelFilter' to `GtkTreeSortable' (users-admin:724): Gtk-CRITICAL **: gtk_tree_sortable_set_sort_column_id: assertion `GTK_IS_TREE_SORTABLE (sortable)' failed What seems to be happening is that the function create_users_model() in users-table.c is creating a GTKTreeModel of type GTK_TREE_MODEL_FILTER instead of eg. plain type GTK_TREE_MODEL. When the code in create_users_table() calls gtk_tree_sortable_set_sort_column_id() this fails because the GTK_TREE_MODEL_FILTER is not sortable. There is some discussion on this issue and a proposed solution here: http://mail.gnome.org/archives/gtk-list/2005-February/msg00177.html This is all I have gleaned so far and may be well wide of the mark, but I shall persevere. -- users-admin does not sort when Name/Login/Homedir field clicked https://bugs.launchpad.net/bugs/259163 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
