Can't load X11 over SSH

Hi all,

I have a problem with my kali 2.0, I've always use the graphical enviroment with X forwarding but in this release I can't use it anymore, I got this messages:

#(gnome-session-failed): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-MZl5w5jq3g: Connection refused
#software acceleration check failed: Child process exited with code 1

I checked the ssh config and the line is:
X11Forwarding yes

thank you all for your help.
