Yes, this is a known problem, though there's no sign that we can fix it soon.

Created an attachment (id=82285)
 --> (http://bugzilla.gnome.org/attachment.cgi?id=82285&action=view)
simplified_test.cc

Here is a simplified test case. It seems to be some problem with GtkAccelGroup
in GTK+. It might be caused by how we use these objects from gtkmm, but I'd
like to see a GTK+ test case to confirm that.

This test produces this output, without the need for any UI interaction:

murrayc ubuntumurrayc:~$ g++ test.cc `pkg-config gtkmm-2.4 --libs --cflags`
murrayc ubuntumurrayc:~$ ./a.out 
debug: before delete window

(a.out:20034): Gtk-CRITICAL **: _gtk_accel_map_remove_group: assertion `entry
!= NULL' failed

(a.out:20034): GLib-GObject-WARNING **: instance of invalid non-instantiatable
type `<invalid>'

When breaking on g_log, we see this backtrace at the first glib warning:

------- Comment #6 from Murray Cumming  2007-02-10 16:07 UTC -------
Actually, it looks like the GtkAccelGroup is being destroyed (finalized) too
early - it should stay alive while it is used by the other GtkUIManager.
gtk_ui_manager_insert_action_group() does seem to g_object_ref() it properly.

A GTK+ test case does seem to be necessary.

I already stumbled about this some time ago, however it seems that the patch
got lost somehow. Refer to http://bugzilla.gnome.org/show_bug.cgi?id=336598.
