[X2Go-User] Always get this error when starting remote desktop, still works though

I am running x2gp on an xubuntu 19.10 system to run another xubuntu 19.10 system's desktop. Whenever I start it up I get a pop-up window that says:-

Connection failed. Cannot create remote file
~chris/.x2go/ssh/key.abiGan - SCP: Warning: status code 1 received:
scp: ~chris/.x2go/ssh: No such file or directory 

But the remote desktop starts up OK. The directory ~chris/.x2go/ssh *does* exist and seems to have reasonable permissions and copying files to that directory using scp on the command line works OK.

Just checked, I get the same error when running individual programs.

While I'm here, another (very minor) issue, x2go leaves a dead symbolic link (i.e. points to a non-existent file) in ~/.x2go on the remote system every time it makes a connection. ... and it leaves a 'real' file of the same name in ~/.x2go on the local system.
