           Summary: Digikam 8.1 Image Editor could not interpret a Nikon
                    Z9 NEF file but I am able to export to JPEG the full
                    size export at 5504 pixel (max length size of the NEF
                    file) to 100% uncompressed JPEG

SUMMARY
***
Attached are the 4 images of the Digikam 8.1.0 of where I installed Digikam in
my Ubuntu 22.04 LTS OS
(Digikam_Bug_0000001.png, Digikam_Bug_0000002.png, Digikam_Bug_0000003.png,
Digikam_Bug_0000004.png). 
Also attached is the NEF file captured from my Nikon Z9 camera with latest
firmware of 4.1 from Nikon 
USA (_DSC0126.NEF). The Digikam software was installed using the GUI interface
that detects all the 
software installed and available software to install for Ubuntu 22.04 LTS. I am
using a Lenovo P620
workstation running Ubuntu 22.04 LTS which was upgraded from Ubuntu 20.04 LTS.
All Ubuntu 22.04 LTS 
updates are using only the Security updates and nothing else. I also have no
customization of the 
Digikam 8.1.0 software installed. 

Digikam is very useful to me because it is better than the Nikon NX-D and have
the same image 
reproduction of Capture One Version 20 which I use for my other Pextax K-1 II
camera. I cannot use 
the Image Editor and adjust the image to my preferred adjustments.
***


STEPS TO REPRODUCE
1.  Import the attached NEF file (_DSC0126.NEF). 
2.  Open the NEF file using the "Image Editor" button.
3.  "Image Editor" will display the message "Cannot decode RAW image
'_DSC0126.NEF'". I am using Adobe
    RGB color space for all my NEF files in case I need to have Adobe RGB in
the future. Please see attached 
    file "Digikam_Bug_0000005.png" image.
4.  I am able to export the NEF file with no compression (100%) but I cannot
use the "Image Editor" to
    make lighting, color adjustments to the NEF file. I only use a NEF file and
not even have any 
    in-camera JPEG file created. Also attached is that exported JPEG image
(_DSC0126.jpg)     

OBSERVED RESULT
1.  Please see attached image (Digikam_Bug_0000005.png)


EXPECTED RESULT
1.  Please see attached image (Digikam_Bug_0000006.png) which is the image for
a Pextax K-1 which I 
    downloaded from the Internet.
