Now done that. Kmail did pick up the subfolder structure in the copy 
of my ~/mail and gradually showed all the emails in there.
  Just had to start kmail and it all started to appear automatically.

   (Ditto with the Mageia-6 on my laptop.)

So - as I had suspected - something in /home/me  is now preventing kmail 
from properly reflecting the contents of ~/mail any more.

The $64 question is: How to find the culprit?!
