I am using a program called Cliosoft SOS. It has a window that displays in columns like an Excel file. When I resize one of the columns then my X2GO session window crashes. The start window where I pick which session to start stays running.
There is a horizontal scroll bar to move the columns sideways. When I drag that then the X2GO window crashes.
I can resize the entire SOS window without any problems.
I do not see this sort of behavior in LibreOffice Calc.
I have attached the session log and the client debug console output showing a few of these crashes.
My client is v. 4.1.2.2 on Windows 10.
I am connecting to a CENTOS 7 system running X2GO 4.1.0.3-9 server which came from the Epel repo.
Is there some way to fix this or is it a bug that I should report?
Is there any additional information that I should gather?
Anything I should ask the software developer?

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: post the output you see.
- start the session as always.
- start an additional ssh session to the server as the same user or root to the server
- 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)
- attach the debugger to the PID: gdb -p PID
- 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
Anything I should ask the software developer?
Well, as written above a test version that triggers the problem would help.

I don't know. I will ask them and I will also try your debugger suggestion. The program requires quite a bit of setup before the columns are seen.

I can always reconnect after one of these crashes and see my desktop with ask the programs still running. When I do then I see that my SOS columns have been resized.

I will try this in the next few days.
