A modified mergeresources.py that exposes this behavior.

Version:           4.6 (using KDE 4.6.0) 
OS:                Linux

I have been playing around with the resource merging in playground:
http://websvn.kde.org/trunk/playground/base/nepomuk-kde/toolbox/mergeresources.py

Using the following query one finds hundreds of duplicates:
select distinct ?people count(?r) where { ?r a nco:PersonContact . ?r
nco:fullname ?people . }

I tried to merge these and I noticed a huge improve in queries afterwards.

Reproducible: Always

Steps to Reproduce:
Install and make use of the nepomuk email, calendar and contact feeders.

Actual Results:  
A duplicate resource is created in nepomuk every time the feeder starts.

Expected Results:  
Each task, contact, email, etc. should only be fed to nepomuk once. Feeders
should properly check for this.

I am posting a modified mergeresources.py that exposes this behavior.
