Bug 276606

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-2-desktop x86_64
Distribution: "openSUSE 12.1 Milestone 2 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: Inside one of folder marked as indexable by nepomuk, I was doing some new reports.  like /sbin/lspci -vvv > lspci.log
The crash happen during the rpm -qav > rpm-qav.log command, it take long time to generate the 4235 lines of log. 

I suppose nepomuk file indexer crash cause the content change during indexation.
Should be easy to emulate with a small script. 

I will try to reproduce it.

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