RawTherapee is terrible with DNG files. I have a lot of Olympus E-M1 images that I had Lightroom convert to DNG. DarkTable handles these files just fine. They are unusable in RawTherapee. The issue is that RawTherapee can only handle Linear DNGs. Linear DNGs are essentially TIFF files where the underlying sensor data has been de-mosaiced and normalized. A Linear DNG retains the higher color depth of the sensor, but it's not RAW. DarkTable has no such limitation. It properly recognizes the underlying CFA scheme (which are different for different sensors), and processes them properly.
