that sounds like a bug ... checking XDG_DATA_DIRS on my trusty system i
see:
ogra at anubis:~/datengrab/snappy$ env|grep XDG_DATA_DIRS
XDG_DATA_DIRS=/usr/share/ubuntu:/usr/share/gnome:/usr/local/share/:/usr/share/

so /usr/local/share is definitely in the searchpaths and apps using the
xdg standard should actually respect /usr/local/share/applications/ if
you created it and added a .desktop file ...
