I had the ForwardX11Trusted yes in my /etc/ssh/ssh_config file already,  
I had seen that in the changelog and searched for a solution based on 
it...  I did try the -Y (which for some reason I didn't notice before) 
and sure enough this worked ...  So I messed around with it and found 
that I needed 2 entries in /etc/ssh_config:

ForwardX11 yes
ForwardX11Trusted yes

for it to work.
