-- Information about the crash:
When using KMail the nepomuk and virtuoso runs beserk using a lot of CPU and making the computer very inresponsive after a while nepomuk stub crashes. I have the google connection in the calendar which might have something to do with it.

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