Description Laurent Bonnaud 2011-07-31 11:48:11 UTC 
Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic-pae i686
Distribution: Ubuntu 11.04

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

I was trying to index my homedir with nepomuk and strigi from KDE 4.7 (I had disabled it in previous KDE versions). I left my computer unattended for several hours and when I came back, nepomukservicestub had crashed.

This is in Ubuntu 11.04 with this package version:

Package: kde-runtime
Version: 4:4.7.0a-0ubuntu1~natty1~ppa1

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

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:

i noticed strigi was indexing files, so i clicked on the search service icon in the system tray, a little window popped showing number of files indexed and storage amount, i clicked close after reading them, the moment it closed, the nepomukservicestub process crashed.

- Unusual behavior I noticed:

strigi never autostarts, even though it's set to do so, whether in the system settings interface, or in config files, it is set to autostart, but it won't, and yes, i do have more than 1 GB of memory, but that's another issue i'll resolve later.

another issue, it is set to index starting from root directory (not home dir), and /dev is a greyed checkbox (as it should be), yet, strigi indexes it.
