I checked the above link and for me, running a fresh install of 9.04, my Kate entries are in:
/home/nigel/.local/share/applications/kde4
and since I had already done the:

System settings->Advanced tab->File bindings. In the treeview select text and then for every 
filetype that has Kate as an option of program to the right, select the kate option and click 
edit, in the dialog that opens select the Program tab and change the Command from kate %U to kate 
--use %U.

I have a file named 'kate --use %U.desktop' (it's the only one in 
'/home/nigel/.local/share/applications/kde4'.
I then, as per the above link, changed the line "X-DBUS-StartupType=Multi" and change the "Multi" 
to "None".
Except that my entry had the 'Multi' as 'multi' -- so I changed it to 'none' rather than 'None' 
(notice the difference in Capital letters!).

Now I am pleased to say that I don't get annoying pop-ups warning me about 'KDEinit launch 
"/usr/bin/kate".

Blessings,
