Package: x2goagent
Version: 4.1.0.3

After upgrading from fedora workstation 32 to fedora workstation 33 I'm no
longer able to use x2go for remote work (I asked a linux workstation and
configured it myself). X2go has been running fine since f31.
Often after a reboot I can still use x2go for some minutes then it starts
to close unexpectedly even after a few seconds or when opening new windows
after session creation.

Here is one of the many core dumps:

Please let me know if you need more info or testing, the problem is always
reproducible.
Thanks in advance,
Gianluca.
