Thanks for the info, Antony!

I must admit that I was only searching the mailing list archive for the
subject concerning "bug" or "tftp", but not the content of the residual
mails before I wrote my bug report.

Good to see that you've already found that commits that cause the
problem. Hopefully it will be fixed in one of the next releases.

Best regards,
