The example/submenu.py works only for get_file_items(), but not for background_items().

It was commented in #440026.

The example provided doesn't show anything when get_background_items() is called.
I guess it happens because the MenuItem created has the same 'id' as get_file_items.

It has:
    # FIXME: Why isn't this working?
    def get_background_items(self, window, file):
        submenu = nautilus.Menu()
        submenu.append_item(nautilus.MenuItem('ExampleMenuProvider::Bar', 'Bar', ''))

        menuitem = nautilus.MenuItem('ExampleMenuProvider::Foo', 'Foo', '')
        menuitem.set_submenu(submenu)

        return menuitem,


However, using a different 'id' it partially works:
    # FIXME: Why isn't this working?
    def get_background_items(self, window, file):
        menuitem = nautilus.MenuItem('ExampleMenuProvider2::Foo2', 'Get foo...',
 '')

        submenu2 = nautilus.Menu()
        menuitem.set_submenu(submenu2)

        menuitem2 = nautilus.MenuItem('ExampleMenuProvider2::Bar2', 'Get bar...'
, '')
        submenu2.append_item(menuitem2)

        return menuitem,

At this stage, it shows only a menu (not the submenu).

However, there was a bug filed in Nautiles just the day after nautilus-python 2.5 was released.

According to #508878 the submenu was not activated.

Without seeing that code yet, I guess something is missing also in the binding that will solve this issue.

I have no experience in bindings, I'll take a look at it.  But any help, tip, code, etc. will be appreciated.
