            Bug ID: 368794
           Summary: digiKam crashes with lossy dng image
           Product: digikam
           Version: 5.1.0
          Platform: MS Windows
                OS: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR

Hello, 
Im am working with digikam 5.1.0 on a windows XP system.

Digikam and also ShowFoto (5.1.0) both crash when I try to open a lossy dng
image.
As long as I work with the embedded preview/thumbnail image only, everything is
fine.

But with access to the "image data" itself both crash. 
I cannot decide whether this happens with all lossy dng images or only with
this specific one, which I found in internet and downloaded for some specific
dcraw tests some years ago.

Reproducible: Always

Steps to Reproduce:
1.Try to edit the lossy dng image.
2.
3.

Actual Results:  
DigiKam and ShowFoto crash.
I do not see any error report on screen.

Expected Results:  
As far as I know is dcraw able to work with lossy dng images.
So digikam should atleast give en error message, in case of it is not able to
work with lossy dng files.

I can send the lossy dng file which has a size of about 17 MB.
Where should I send it to?

Thanks in advance.
Best Regards
Herb
