CHDK DNG issue - dt 3.0 [CLOSED]

when opening dng files from a chdk point-and-shoot, it gives this error, shows strange black borders, and presents really faded colors.
Opening the same file on RT 5.7 presents no issues.
is this a bug?

dt 3.0rc1-git41.e15db

RT 5.7

dng file: IMG_5865.DNG (17.8 MB)

This issue has been fixed.
Thanks devs!
For the record, I had to restart Darktable from scratch, that is, a clean .config/darktable folder, in order to see the effects of the fix.
Thanks devs once more.
