That sort of works.

As Julie Lavergne noted today in a post with Subject: 'Back on 13.10 
release,' lxsession-edit (Preferences: Desktop Session Settings) has 
been removed from 13.10.  It has been replaced by lxsession-default-apps 
(Preferences: Default Applications for LXSession).  I think you and I 
had some previous exchange on this topic.

But the layout and functionality of lxsession-default-apps seem 
confusing.  You might think that its Autostart tab was intended to 
replace lxsession-edit's functionality, but as far as I can tell so far, 
it's major function is to disable/enable whole classes of autostarting 
apps.  There seems to be a provision for manually adding and controlling 
single apps, but there is no pre-populated list as there was with 
lxsession-edit.

In any case, on the Running Applications tab, I edited Network GUI: 
nm-applet and set that to NO.  This results in only one instance of 
nm-applet running for that user.  The edit must be repeated for all 
users.  [There is undoubtedly a global configuration that would fix 
that, but it does not seem to be achievable through the GUI, and I have 
not found documentation for accomplishing that directly in a 
configuration file.]

But I still don't know where the other instance of nm-applet is 
launching from.  /etc/xdg/lxsession/Lubuntu/autostart is empty, as is 
~/.config/lxsession/Lubuntu/autostart.  And there is no *.desktop entry 
for nm-applet in the ~/.config/autostart folder.
