Same problem here with kdesudo, if i run "kdesudo dolphin", i've got this error message: "Cannot run the process. Cannot talk with klauncher: The name org.kde.klauncher was not provided by any .service files".
It work fine also for me if i run "kdesudo konqueror", close it and run again "kdesudo dolphin" or if i run "gksudo dolphin".
