In Smuxi when you rejoin a channel this will lead to exception after upgrading from GTK# 2.12.10 to 2.12.40 like this: System.NullReferenceException: Object reference not set to an instance of an object at GLib.GType.GetQualifiedName (System.String cname) [0x0005d] in <8c54b02ecd9b45db868abfb5696ef2d4>:0 at GLib.GType.LookupType (System.IntPtr typeid) [0x00020] in <8c54b02ecd9b45db868abfb5696ef2d4>:0 at GLib.ObjectManager.GetTypeOrParent (System.IntPtr obj) [0x00007] in <8c54b02ecd9b45db868abfb5696ef2d4>:0 at GLib.ObjectManager.CreateObject (System.IntPtr raw) [0x00012] in <8c54b02ecd9b45db868abfb5696ef2d4>:0 at GLib.Object.GetObject (System.IntPtr o, System.Boolean owned_ref) [0x00074] in <8c54b02ecd9b45db868abfb5696ef2d4>:0 at Gtk.TreeModelAdapter.GetObject (System.IntPtr handle, System.Boolean owned) [0x00000] in <8bc02e9c110240acb0e1344122d80ad3>:0 at Gtk.TreeView.get_Model () [0x0000c] in <8bc02e9c110240acb0e1344122d80ad3>:0 at Smuxi.Frontend.Gnome.GroupChatView.Populate () [0x0004c] in /tmp/buildd/smuxi-1.0.6/src/Frontend-GNOME/Views/Chats/GroupChatView.cs:325 at Smuxi.Frontend.Gnome.ChatViewManager+<OnChatSynced>c__AnonStorey1.<>m__0 () [0x0007b] in /tmp/buildd/smuxi-1.0.6/src/Frontend-GNOME/ChatViewManager.cs:351 at GLib.Idle+IdleProxy.Handler (System.IntPtr data) [0x0003c] in <8c54b02ecd9b45db868abfb5696ef2d4>:0 And the console output will show GTK/GLib CRITICAL messages: (smuxi-frontend-gnome:1992): Gtk-CRITICAL **: IA__gtk_list_store_clear: assertion 'GTK_IS_LIST_STORE (list_store)' failed (smuxi-frontend-gnome:1992): Gtk-CRITICAL **: IA__gtk_tree_view_set_model: assertion 'model == NULL || GTK_IS_TREE_MODEL (model)' failed (smuxi-frontend-gnome:1992): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed (smuxi-frontend-gnome:1992): Gtk-CRITICAL **: IA__gtk_list_store_clear: assertion 'GTK_IS_LIST_STORE (list_store)' failed (smuxi-frontend-gnome:1992): GLib-GObject-CRITICAL **: g_object_remove_toggle_ref: assertion 'G_IS_OBJECT (object)' failed (smuxi-frontend-gnome:1992): GLib-GObject-CRITICAL **: g_object_remove_toggle_ref: assertion 'G_IS_OBJECT (object)' failed (smuxi-frontend-gnome:1992): GLib-GObject-CRITICAL **: g_object_remove_toggle_ref: assertion 'G_IS_OBJECT (object)' failed (smuxi-frontend-gnome:1992): GLib-GObject-CRITICAL **: g_object_remove_toggle_ref: assertion 'G_IS_OBJECT (object)' failed This has never been a problem though with GTK# < 2.12.40, which makes this a regression of GTK# 2.12.40 I have debugged the issue already and found the fix in the stable branch of upstream's git repository here: https://github.com/mono/gtk-sharp/commit/4ac71507fffce997207215ac3f8b38471ce60a14#commitcomment-21776072 So I will backport that fix and request a freeze exception as this bug affects all GTK# users that use the Gtk.TreeView and replace the model.
