So Bug #1682755 was not really a bug. I am sorry for the inconvenience caused by my lack of knowledge in the system.
Brian Murray showed me the problem and the way to resolve it. I have to apologize to Brian that I called "Bill" in a eMail is showed here. It was a mistake, but, you know, I'm getting old... Many thanks to all the people that worked to help me.
