Fresh upgrade from this morning. Below are some debug client logs. I also posted to pastebin a crash log from the Mac crash submit tool before hitting send:

Any clue what this could be? I've tried with a local user and NIS user. This is Fedora 26 workstation but oddly to Fedora 26 server it works with both. There must be something with a configuration that is blocking X2Go. We've tried a plain vanilla .bashrc and .bash_profile, no difference. Also have deleted the .x2go directory of each user, restarted dbus, systemd-logind and x2goserver. We are using the nightly builds and the COPR report for nx-libs.

From the server logs:
