I saw a strange option during the process.

Attached the screenshot.

I do confirm the the error but... in spite of the error notification... the course was restored.

From Ray Lawrence (ray at howtomoodle.com) Wednesday, 12 July 2006, 11:03 PM:

I've isolated this issue to the course creator not being a Teacher in the course being restored. Is this the expected behaviour or a bug?

From paolo oprandi (paolo at sussex.ac.uk) Wednesday, 12 July 2006, 11:36 PM:

Ray, I'd call it slightly buggy - the error message shouldn't be thrown. It is related to the bug I have filed:

Thanks Paolo. I'm watching that bug too. Unfortunately I won't have time to do much more testing on this in the near future.

Without this modification, the restore process finishes correctly (i.e. the whole course is properly restored), the only thing that is not completed is adding the current user as a teacher to the newly created course:

line 5355: $status = add_teacher($USER->id, $restore->course_id);

as the $USER->id is not available to it.

it seems to have sense, so I've applied your suggestion to 1.6! Thanks!
