Hi!

I had this same problem and my solution works quite well (see attached files). 
You will have to change a bit in the files, however I hope this could help 
you.

If you have any questions about the desktop-file of shell script, please 
ask :)

--Thomas

P.S.: I'm sending this to kde-devel, too, in case someone is interested :)
