Recent file menus and item states not updating correctly

[nohamelin]

Giving a try to the current gaupol-master in a live session of Fedora 24 Workstation:

• Create a new document, add a new subtitle and the respective translation.
• Save both files, and close the tab.
• Now there aren't open files. Open the File menu: note that the menuitem "Open translation" is disabled, but the submenu "Open recent translations" have enabled subentries. Clicking in one of these files triggers the next error:

File: /home/liveuser/Downloads/gaupol-master/gaupol/agents/menu.py

    self.open_translation(action.gaupol_path)

    return function(_args, *_kwargs)

Good catch. With Gio.Action etc. I cannot disable whole submenus, which is what I used to do before, but items themselves can be disabled. Also, the recent menus seem to be blank before before opening or saving a file and that's not right either.
