I'm mostly a Windows guy, but I have the following in the setup notes I 
have been keeping for my Fedora system:

To make an icon that runs dolphin file manager as root under Fedora 10, use
  kdesu dbus-launch dolphin %i -caption "%c" "%u"

I'm on Fedora 15 now, but still using the above.  For a program that's set 
UID, maybe try just dbus-launch without kdesu.
