I guess it must be the kdelibs(-common)-4.4.0-3 update from yesterday, or maybe soprano/sesame2. I do not think it can be virtuoso, as I was aware of the upcoming change, so I deleted the entire contents of: ~.kde/share/apps/nepomuk/repositary/main/data/virtuosobackend prior to upgrading virtuoso, but I am still not able to achieve a KDE session.
