Thank you for taking the time to file a bug report.

The Nepomuk project is no longer included in the KDE Software Compilation. With Plasma 5, we have replaced most of the underlying technology with Baloo and other components. Hopefully this will have addressed your concern.

We encourage you to try out Plasma 5 (+Baloo) and let us know if your problem persists.
