I can confirm the same problem as Charles Figura. I'm using Kubuntu and I don't have a Contacts runner, only Nepomuk.
However, the problem only occurs when using the new Akonadi-enabled PIM suite with Akonadi 1.4.95. Disabling Akonadi and restarting Nepomuk makes virtuoso-t behave as a normal process.
