One from location ~/kde/share/kde4/services/nepomukcontroller2 and one from ~/kde/share/kde4/services/nepomukcontroller. Because of this, plugin is loaded twice. Or it is possible that only one file actually exists, but ksycoca cached both entries.

No need to be sorry. Apparently I did cause it myself by not renaming properly. :/

Now it works, here, too.

Now how about some start/stop service actions?
