You are replacing a directory with an ordinary file. The requires a
%pretrans script. %pretrans scripts must be written in lua:

%pretrans -p <lua>
st = posix.stat("%{_datadir}/applications/%{name}.desktop")
if st and st.type == "directory" then
   os.execute("rm -rf %{_datadir}/applications/%{name}.desktop")
end

Wow.  Shouldn't RPM support this out of the box?
