Comment 1 Anne-Marie Mahfouf 2010-11-29 21:29:36 UTC 
Did you reproduce it? Did you try with default settings?
The duplicates are all older and solved so it wouldbe good to know if you reproduce it.
Comment 2 Nikolay Rysev 2010-11-29 21:37:00 UTC 
No, I can't reproduce it now with clean ~/.kde4

Thanks.
