Description maninred 2011-07-06 19:02:54 UTC 
Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.5 (4.6.5) "release 8"
Qt Version: 4.7.4
Operating System: Linux 3.0.0-rc5-1-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I´ve here several textcorpi and webcrawls on my harddisk wich are there for later processing.
Seems to be that nepomuk try to index it and get with this a kind of fuzzing, because of the many different files.
Just a suggestion.

-- Backtrace:
Application: Nepomuk-Dienst (nepomukservicestub), signal: Segmentation fault

Closing as WONTFIX since the crashing code does not exist in KDE 4.7 anymore.
