I have output everything that appears, I've not changed it at all.
It's the whole content of the file ~/tmp/mail.err as it's the only
error that has occurred for the last day or so.  The error log is
created by the line:-

    sys.stderr = open("/home/chris/tmp/mail.err", 'a')

So that's everything that was output to stderr.

I think you are puzzled in the same way that I was, the error message
doesn't make a lot of sense.
