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.
