If you are having the software manager close on you after 3 seconds or so try this:-
Go into application launcher and search for Nepomuk Fille Indexing Controller and just click on it. Then go back into software manager and you should find it will open. I have tried this and it works using mint 12 KDE. Hope this helps someone out
Thanks also to Coyote who helped out with this on the Quassel IRC client for mint 12
