Is that program available for testing?

The session log looks like a reconnect should be possible. Can you confirm?

It is a bug - nx should not crash.

Well, you could try the following:
1. start the session as always.
2. start an additional ssh session to the server as the same user or
root to the server
3. run pgrep x2goagent and note the resulting PID (if you have
multiple session running you will find multiple PIDs and need to
identify the correct one)
4. attach the debugger to the PID: gdb -p PID
5. then try to provoke the crash. If it happens the debugger should
kick in and show a prompt. Run the "bt" in command in the debugger and
post the output you see.

Well, as written above a test version that triggers the problem would help.
