Yep. Leaving behind too many maybe-bugs can make the ground swampy.

I forgot to mention that the theory of David Wright is not outruled yet:

Loop and size overflow could indeed have been separated.
- First some step-on-own-foot loop would have created the deep directory
  tree until it failed due to path size. May have happened months ago.
  Now barely legal paths are lurking.
- This would then cause another failure when a non-looping copy attempt
  lengthens the path by prefix "/media/richard/MISCbackups/dev_sda14".

Richard would have to check whether there is such a deep tree on the disk
that shall be source of the copy.


Have a nice day :)
