Please describe the problem:
It's impossible to change permission over a ssh folder connection

Steps to reproduce:
1. Connect to a serveur, 
2. Then, type of the serveur: ssh , serveur : your machine , Folder : your home folder, user : your user connected
3. Type you password
4. ON the new nautilus opened, try to change a permission on a file : you can't change the permission

Actual results:
Can't change permission on a file or a folder

Expected results:
Can change the permission

Does this happen every time?
Yes

Other information:
This folder connection is very userful for manage lot of data in different serveurs.
To by passe this problem, we need to open a terminal, open a ssh connection to the serveur imvolved and change the permission ( chmod or/and chown ) in the command line...
