yes, i can import 4000 image from my external HDD. No crash here. Both on
my desktop (8Gb) and my laptop (3Gb). I can follow memory allocation
without to see any memory leak.

So i suspect something wrong into an external dependency of digiKam, as
libraw (if you import RAW file), or libexiv2 to read metadata and fill DB.

The valgrind trace is not enough informative.

To you import only JPEG, or RAW, or RAW+JPEG ?
