Comment 1 Laurent Montel 2013-08-23 08:14:37 UTC 
a lot of fixes was done in 4.11
could you retry with 4.11 ?
Comment 2 hugo_m6XB 2013-08-23 12:46:45 UTC 
Ok. I will retry it.  According to http://de.opensuse.org/KDE_Repositorys
I could use an upstream Release:   KDE SC 4.11.

Comment 4 Vishesh Handa 2015-01-23 16:22:09 UTC 
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.
