On another server that works OK I just killed an X2Go session from August!

I'm having a colleague test and I'll do the same this weekend.

Can I provide anything else? Could NIS be contributing to this?

It fails with NIS users and local users. On the working and non-working
machine, I try with a local user and both $HOME are set as follows:
echo $HOME
/home/localguy

We've also tried to use a plain-vanilla .bashrc and .bash_profile, no
difference.

Could there be any other installed package causing a conflict?

This also fails from a PC 4.1.0.0 client, BTW some logs:
