Bug 270844

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu Natty (development branch)

-- Information about the crash:
"Nepomuk Service Stub" srached while indexing files.
Nepomuk started indexing files after I generated a lot of files in one of ites monitored directories.

Shortly after it crashed.

This is somewhan random and I can't reproduce it reliably.

Thanks.

The crash can be reproduced some of the time.
