The crash is in libkexiv2, when preview are get from file to render
image on screen.

I ready fixed this problem in source code.

There is a report which still open about this topic, where i annotate
which simple commit i do to fix it in libkexiv2 :

https://bugs.kde.org/show_bug.cgi?id=339144

I upgraded libkexiv2 version to 2.3.2. If digiKam do not use this
version it will crash.

digiKam have been released with this version of libkexiv2, but
packager drop libkexiv2 source code from tarball and use system based
library.

The solution from packager is to backport my little commit in libkexiv2 package.
