sni-qt creates hundrets of statusnotifiritems on Plasma-desktop

after installation of sni-qt in my kubuntu and restart the systemtray is full of invisible notifieritems. if i klick on the freespace, the terminal output is:

plasma-desktop(9222)/plasma StatusNotifierItemSource::contextMenu: Could not find DBusMenu interface, falling back to calling ContextMenu()

the config dialog looks like this:
