Bug 278601

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
Every time I startup my machine, virtuoso consumes a lot cpu power(2 of 4 cores are working 100%)! The only think I can do is to kill the process(virtuoso -t) in terminal. This crash report came up a couple of minutes after I killed virtuoso.

-- Backtrace:
Application: Nepomuk Service Stub (nepomukservicestub), signal: Aborted
