Gtk::ActionGroup in two Gtk::UIManager

[Frank Naumann <fnaumann boerde de>]

Hello!

It's possible to use an ActionGroup in more than one UIManager?

I like to construct a popup menu with a separate UIManager with usage of 
an existing ActionGroup used by another UIManager.

It works ok so far just that on destruction of the UIManager/ActionGroup 
the gtk+ runtime print out several errors:

(easyEDD.exe:4591): Gtk-CRITICAL **: _gtk_accel_map_remove_group: 
assertion `entry != NULL' failed

(easyEDD.exe:4591): GLib-GObject-WARNING **: instance with invalid (NULL) 
class pointer

(easyEDD.exe:4591): GLib-GObject-CRITICAL **: 
g_signal_handlers_disconnect_matched: assertion `G_TYPE_CHECK_INSTANCE 
(instance)' failed

(easyEDD.exe:4591): Gtk-CRITICAL **: gtk_accel_group_disconnect: assertion 
`GTK_IS_ACCEL_GROUP (accel_group)' failed
