Thanks for putting me right on tracks, then. I don't think I've dreamed,
though.

Next time I need to track down some error, and get a backtrace, I'll be much
more careful for testing, and report anything I would consider as being wrong.

Up to that point, then, I'm presumed to be wrong.

Best regards,
  Seb
