xfce4-popup-applicationsmenu does not interpret <OnlyUnallocated/> menu spec

The xfce4-popup-applicationsmenu in "trusty" does not properly interpret <OnlyUnallocated/> and <Exclude> perimeters in freedesktop menu specifications. In "raring" it did. libgaracon-1-0 does not seem to be the issue, as the Applications menu available when right-clicking on the Xubuntu desktop does not suffer from the issue, nor does the new "Whisker Menu."

Whenever a foo.desktop files are placed within a sub-menu (e.g., CardGame) of a freedesktop.org registered main menu category (e.g., Games), the entire main menu category fails to read. It reads as expected in the Applications menu available when right-clicking on the Xubuntu desktop.

So, in xfce-applications.menu, when all foo.desktop files are in sub-menus, the entire main menu category is gone. To get the main category back, I must comment out the Exclude element, which results in DUPLICATE entries in both the Main and Sub-Menu.

<!-- <Exclude>
            <Filename>DJL.desktop</Filename>
</Exclude> -->

The same behavior happens when using <OnlyUnallocated/>. When all foo.desktop files are allocated in to sub-menus, the entire main menu category is gone. To get the main category back, I must comment out the OnlyUnallocated element, which again results in DUPLICATE entries in both the Main and Sub-Menu.

See the attached screenshots.
