Bug Description

 Thumbnails for raw format photo files aren't visible in the file manager in Mint Debian,a blank placeholder or randomly a generic image icon are displayed instead.
 I'm reporting this referring to Canon raw files with .CR2 extension,but actually other equivalents (as . NEF or .PEF for instance) also have the same issue-furthermore,I'm seeing this on Mint Debian but I've also checked with Mint 13 and it has the same behavior.
Whilst these files are displayed with a proper thumbnail in Nautilus in Ubuntu (installing libopenraw1,libopenraw-gnome and related packages ),in Mint Debian no proper thumbnail is visible either using Caja or Nautilus (in this case,even with the packages named above installed),and this bug extends to gThumb as well,as no thumbnails at all (not even placeholders) for raw images are visible in gThumb,even if the actual image can be opened.
For comparison,XnView 0.51 displays these thumbnails correctly in Mint Debian.

1)Linux mintdebian 3.2.0-3-amd64 x86_64 GNU/Linux (Mate)

2)Download/import any .CR2 image file (or equivalent),then open the file manager to see the image preview and launch gThumb to browse the folder

3)No thumbnail is visible either in file manager (Caja or Nautilus) and gThumb

4)Thumbnails (image preview) for raw image files should be visible in the file manager and in gThumb

5)Always happens with all raw .CR2 files (and equivalents)

I am affected by this as well but the extension used by Nikon is .NEF

I installed gnome-raw-thumbnailer and that fixed part of the problem. In a directory listing of 125 files, nemo only displays half the thumbnails. This is better than none. All would be great!

In my case,even after trying the known workaround described here https://bugs.launchpad.net/ubuntu/+source/gnome-raw-thumbnailer/+bug/852923 I still can't see a single .CR2 thumbnail,neither in Caja (as I'm using MATE ) or gThumb - and this actually involves all raw format photo files,not just .CR2 from Canon.

Hello Ubuntu/Mint community,
There used to be a RAW photos preview support in caja in Mint 19.x if I remember correctly. Now, on Ulyana there is no more thumbnail preview. It is really slowing down working with photos edition. It would really be a great help for photographers to bring the preview back.
Best regards,
Alfred

This is fixed with xapp-raw-thumbnailer.
