version 5.5.0 do not exists. Which digiKam version you use exactly ?

The KRA image is managed through a dedicated Image loader, provided separately
by KDE.

You have reason. Is Digikam 5.3 version. Anyway, I can see that Digikam is
showing some KRA files thumbnails, but not others, so I can't understand what's
the problem.

Well, i suspect a packaging problem.

To confirm try to use current development digiKam AppImage bundle for Linux
available here :

Hi Gilles

I tried the appimage, and sadly it shows nothing for KRA files (an empty
square) without any image content (canvas size) information.

Problem reproducible here with AppImage too :

digikam.metaengine: Cannot load metadata from file   (Error # 11 :
/home/gilles/Images/DSC00604.kra: The file contains data of an unknown image
type
digikam.general: Trying to load Embedded preview with libraw

...even if KRA Qt image loader from KImageFormats framework is installed in the
bundle :
