Version: (using KDE Devel) Installed from: Compiled sources As the short description says. The drag is not recognised as being from the same widget.
Sorry, but I can't reproduce this one. Any chance to get more information? Currently it WORKSFORME. :-)
I forgot to say it is when the view is used in KFileDialog. Add a few user directories in dolphin, open kwrite, save as, drag directories around the places view, and they multiply.
Sorry, can't reproduce...
