krunner showing non existing VT sessions in parallel to existing ones

Opens a new session with the applet from desktop. 
You will find that krunner opens as expected but that for every VT session
opened there is a "ghost session" showing the very same VT as unused. 
When you logout from several users these ghosts persist up to a complete
reboot. 

VT sessions once closed should be closed without residual VTs showing up.
VT sessions open should not be accompanied by a VT session ghost telling unused
session. 

I attach a screen-shot to make the thing clearer. 

Repeatable always.
