Bug 280254

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

-- 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
