Yes I have used fuser. That is why I say all kde apps + a lot more.
IE klauncher, kded4, kgglobalc, knotify4, plasma-de, kio_file, kaccess, kxkb, 
nepomukse, krunner, kmix, kalarm, kgps, kget, polkit-gn, kupdateap, klipper, 
konsol, . . .  and such as yast, openoffice and other running apps.
Now I did check again. I would say that every running program have the 
directory open if I use KDE.
What are all this apps doing in /local/Documents.
If they had followed the link I could have understood but am still 
questioning, what do they have to do here?

Is this a bug or by intention?

So all apps hold an equivalent to /home open ??
A ls here will looks the same as ls /home.
However this might never be used as I as my knowledge not have heard any 
complaints that documents go to this directory. But on the other hand I am 
perhaps the only one using KDE now. All others have changed to other window 
managers. 

Perhaps this is related to the problems KDE has to keep track of following 
links. I has the tendency to change to the real patch instead. This cause 
sever problems and the user have to be very alert.
