I am in favor of such a change.

Using kde4/<something> instead of kde4-<something> works fine with
g_desktop_app_info_new, (even if the documentation[0] does not
explicitely say so), while using only <something> fails, which makes the
current wording confusing even for gnome applications.

I would, in principle, prefer using a destop-file id as described in the
menu spec[1], but I am willing to understand that it's not practical
outside of gnome's implementation.
