I was *not* importing from a memory card, but a folder from my
collection. What I see is that digikam scans the whole folder and then
it does some processing (I did not check the code, it is the behavior I
see). In that second phase it uses an enormous amount of memory.

It is *not* enabled (and anyway I was not importing from camera).
At the moment I am reading jpgs only (I disabled raw and tif files).
