the library dimg which is used to view and access raw 16-bit images in the image editor fails to view the .NEF image taken by nikon D40. It shows multiple lines, probably errors while reading the image.

Reproducible: Always

Steps to Reproduce:
1.Open any existing .nef file in any album in the image editor
2.
3.
Actual Results:  
Sometimes digikam crashes altogether, and sometimes there are errors while showing the photo.

Expected Results:  
Display the image without extra lines, and errors while reading the image

Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
