-- 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.
