Hi David,

I have set up a test VM for this issue today and I can absolute  
confirm what you report.

I will investigate on that further today/tomorrow, and I am quite sure  
of being able to exploit this without X2Go as well.

My guess is a mis-configuration in Linux mint around the local X-Server.
