Bug 279499

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.00 (4.7.0) (Compiled from sources)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-gentoo-r2 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I was downloading some file with Mozilla Firefox. This adds a .part file besides the downloaded file to the Downloads folder, in my home.
- Unusual behavior I noticed:
Nepomuk was active like crazy, the system tray icon was basically blinking, being displayed then hiding (or maybe the app just finished) itself in a loop. I think the nepomuk service should be run in a less intrusive way, maybe once per hour or something like that.

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