Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.10.3
Qt Version: 4.8.4
Operating System: Linux 3.8.0-21-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
Login process
- Unusual behavior I noticed:
besides Nepomuk,
   1) now and then plasma crashes after relatively long slices of user inactivity
   2) sudo get stuck by updates

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