Please, file a bug against Kubuntu. Historically, there have been problems with 3 packages essential to Nepomuk/Akonadi: strigi; soprano and akonadi. Strangely, they are not covered by Kubuntu official PPAs, and if those packages are not updated to their latest releases, you WILL face problems. Currently:
- Strigi is at 0.7.7.
- Akonadi is at 1.6.90 (for KDE SC 4.8)
- Soprano is at 2.7.4 (2.7.5 is imminent).
