Bug 281293

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.00 (4.7.0) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 3.0.4-gentoo-Franklin x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I was in the process of converting an AVI to a format that is compatible with a house hold DVD player.   We are using devede and it's still running.  I left the computer for about 25 minutes and when I came back, I moved the mouse to remove the screen saver and Nepomuk Stub or whatever crashed.  The Nepomuk thing has crashed many times lately.  I have been moving files from a customers two hard drives to my machine and it almost always crashes or shortly after i login into X-Windows

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