Description Diego Agulló 2011-08-01 14:50:28 UTC 
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 x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

I was working on photos, doing some basic editing and organizative stuff (changing the width using gwenview, removing duplicates with digikam and then uploading photos to picasaweb using gwenview again). Just after closing gwenview, nepomuk suddenly crashed. digikam was closed long before that.

-- Backtrace:
Application: Matriz de servicio Nepomuk (nepomukservicestub), signal: Aborted

Sebastian, for now i'm no longer getting the crashes. Using kde-{libs, runtime, workspace} from KDE/4.7 branch, strigi from git master and latest s-d-o (0.8)

New crash information added by DrKonqi

nepomukservicestub (0.2) on KDE Platform 4.7.00 (4.7.0) using Qt 4.7.2

- What I was doing when the application crashed:

Standard text editing. New files were not added in a huge quantity, so it should not affect the nepomuk work.
