Describe the bug

RAWs shot with Intelligent ISO on the camera Panasonic DMC-FZ50 do not load as the color matrix cannot be found for the image.

Steps to reproduce

  1. Import the two images from these zips into lighttable:
  2. Open the file fixed ISO.RAW in darkroom
  3. Open the file intelligent ISO.RAW in darkroom

Expected behavior

Darktable should load and render both RAW files in both lighttable and darkroom.

Nothing to do w/ color matrix or white balance (temperature)... I'm afraid the error comes much earlier, the file cannot be decoded by RawSpeed:

[rawspeed] (intelligent ISO.RAW) virtual rawspeed::RawImage rawspeed::Rw2Decoder::decodeRawInternal(), line 81: Unexpected image dimensions found: (3770; 2799)

Furthermore, this is strange to say the least: image

This is very unfortunate as we have fixed the sensor crops for the one mode, and there is apparently no way to tell the modes apart...

17367 should improve the error reporting so that users are told the file is unsupported rather than having white balance issues.

Do I understand correctly that iISO will not be supported by darktable?
