How can this be still UNCONFIRMED when there are so many duplicates?
Because UNCONFIRMED has nothing to do with how many duplicates exist. Give a detailed way how to reproduce this with a new user, wait until someone can confirm this works on his pc, and then this bug can be set to confirmed.

Marking as confirmed. (To make Newman happy) This can be reproduced by repeated killing virtuoso while running a large number of queries one after another.
The same happens for me. It is a recurrent error. Everytime Nepomuk is running for about 20 minutes it crashes. When I restart it happens again. Tried do delete every configs associated with nepomuk and all the folder .kde/share/nepomuk → happens again.

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.
