The issue has been addressed in Debian, a fix is on its way.

See Debian bugs #940104 [1] (issue report) and #940548 [2].

For further information refer to those two bugs on the Debian bug tracker.

As this issue is not an X2Go upstream issue, I will close this bug here.

Thanks+Greets+Sorry-for-the-inconvenience,
Mike

Package: nxagent

Version: 2:3.5.99.19-3+deb10u1

Severity: critical

Since Debian Buster was updated to 10.1 nxagent (x2goagent) does not work anymore.
A core file is written to the home directory of the user that wants to work with x2go.

Here are the versions from nxagent and x2go server
$ dpkg -l nxagent
Desired=Unknown/Install/Remove/Purge/Hold

I am using the official Debian repo and not the x2go repo because all new stuff should be in Debian.

Here is the log from x2goagent session.log
$ cat  /home/<user>/.x2go/C-<user>-50-1568134622_stDXFCE_dp32/session.log

running as X2Go Agent

I changed the log information in x2goserver (/etc/x2go/x2goserver.conf)
to debug and here is the log:
