[X2Go-Dev] Bug#1073: XSession-x2go: Hostname not set correctly

Package: x2goserver-xsession Version 4.1.0.0-0~1355~ubuntu16.04.1

When trying to start an LXDE x2go session on an Ubuntu 16.04.1 LTS x64 server via a Windows client, I get a black screen with a white dialog saying "XSession-x2go: Hostname not set correctly; aborting."

Debug logging doesn't have much more detail:
