Bug#479761: gnome-menus cannot handle sub-categories with same name

[Ximin Luo]

Package: gnome-menus
Version: 2.22.1-1
Severity: important

This bug is related to:
#444587 - a symptom of this bug
#478839 - not actually fixed, due to this bug

gnome-menus cannot handle subcategories which have the same name. for example:

the existence of the Debian/Games/Board category (defined at 
/var/lib/menu-xdg/desktop-directories/menu-xdg/debian-games-board.directory) BLOCKS the display (and 
the subsequent categorisation of its children into it) of the Games/Board category (defined at
/usr/share/desktop-directories/BoardGames.directory)

This can be easily verified by installing a "board game", eg gnome-mastermind. Its subcategory, "Games/Board", 
fails to show up in the menu, because of the conflicting "Debian/Games/Board" category.

$ tail -n1 /usr/share/applications/gnome-mastermind.desktop 
Categories=GNOME;GTK;Game;BoardGame;

On the other hand, installing a "logic game", eg golly, *does* make the subcategory "Games/Logic" show up, 
because there is no conflicting "Debian/Games/Logic" category (or any other categories named "logic")

$ tail -n1 /usr/share/applications/golly.desktop 
Categories=Game;LogicGame;
