[X2go-dev] X11 connection rejected because of wrong authentication

Hello,

Since I've updated to Debian Wheezy x2go stopped working with no error in auth.log. But X gives: "X11 connection rejected because of wrong authentication" X apps open with manual ssh connection. On one update of xorg, X2go started working but only for the first session. I tried removing the .Xauthority file and it gets recreated, but still the same. Is there a way to check what magic cockie is it looking for?

rat@rat:~$ xauth list hostname/unix:51 MIT-MAGIC-COOKIE-1 494593eXXXX6a44b44487fcd91fbe6fa hostname.net:51 MIT-MAGIC-COOKIE-1 494593eXXXX6a44b44487fcd91fbe6fa

Any help is appreciated. Thanks in advance.
