Comment 18 for bug 1169243

Hmmm... Please, upgrade again. Sorry for being like a broken record, but KDE 4.10.3 has a rewritten Akonadi-Nepomuk feeder, and that can make the difference here. Check you have Akonadi 1.9.2. After that, run the command set and let the Nepomuk Cleaner work until it successfully ends.

After you upgrade, and run those commands, restart your computer.
