Package: x2goserver-xsession
Version: 4.0.1.13

After Gentoo has removed version 4.0.1.6 from its repository, I was
forced to update my installation of x2goserver. However, I cannot
connect to the machine from a a remote system anymore. I have tried
starting KDE and XCFE sessions, but both kind of sessions are terminated
immediately. I can, however, start individual applications, such as
Konsole, Thunderbird, or even Steam remotely.

System configuration is as follows
on server: x2goserver 4.0.1.13, nx 3.5.0.22
on remote: x2goclient 4.0.1.3

As instructed by sunweaver on irc, I'm attaching Gentoo's current
/etc/X11/Sessions/Xsession script.

You can test for Gentoo by checking /etc/gentoo-release.
