Description Ted Cash 2021-03-28 21:33:27 UTC 
SUMMARY
Scanning some DNG photos causes program to exit immediately.

STEPS TO REPRODUCE
1. Scan files to Add Collection
2. Program exits if certain .DNG files are present
3. All .DNG files were created with Adobe DNG Converter.  Most files created do not produce a problem.
4. I have about 10 files that will cause the program to crash every time.  Lightroom sees no problem with these files.

Please share a DNG file to try to reproduce the dysfunction. Use cloud web service as GDrive for example.

Thanks in advance

Ted, 

We needs DNG samples created with Adobe Tool to identify the problem. 

Please use a cloud storage web service to share DNG. 

Thanks in advance.

Ted,

If you cannot share defect DNG files, at least give us which camera model you use exactly ?

Best

Using last 2021 Adobe DNG Converter for MacOS, i generated plenty of DNG files from my huge RAW files collection used for testing digiKam. RAW files type come from many camera with different Raw format (NEF, CR2, CR3, ARW, ORF, etc...)

All can be handle by digiKam 7.3.0 after upgrading DNG SDK to 1.5 and libraw to 20210504 snapshot.

I close this file now. Reopen if necessary.
