Thank you very much for the proper details. I've looked up the reported lines in the error message, it's a tiny mistake, happens only under very rare circumstances. You can safely ignore this warning, it will not cause any issues.
If you want me to fix it directly on your server, then feel free to add temporary FTP details to your ticket, and I will do it of course. I will however patch this in the upcoming release as well.Best,
