Description Maxim 2017-04-21 11:39:52 UTC 
I'm using ufraw-thumbnailer in Arch linux, but after upgrading from 3.22 to 3.24 and some investigation I don't see any thumbnails of my Canon's CR2 files. And if I downgrade gnome-desktop to 3.22 then thumbnails are shown again. It is happend after https://git.gnome.org/browse/gnome-desktop/commit/?id=b69fde6f4a709f8c4fa3087941cee5b4c4169a8d
Comment 1 Bastien Nocera 2017-04-21 12:03:07 UTC 
Yes, as expected. See how it was solved for librsvg in bug 778666.
Comment 2 Maxim 2017-04-21 12:20:29 UTC 
Do I need to notify the developers of ufraw instead GNOME?
Comment 3 Bastien Nocera 2017-04-21 12:33:24 UTC 
Yes, it's up to the developers shipping additional gdk-pixbuf loaders to ship the new .thumbnailer file.

>Yes, it's up to the developers shipping additional gdk-pixbuf loaders to ship the new .thumbnailer file.

Now I'm trying to 

>gdk-pixbuf-thumbnailer input.cr2 output

and gdk-pixbuf also working with extracting thumbnails from CR2 files

You can download CR2 samples and try to use gdk-pixbuf-thumbnailer

Maybe instead of using external ufraw.thumbnailer I need to use gdk-pixbuf?
Comment 5 Maxim 2017-04-21 13:02:48 UTC 
I deleted ufraw.thumbnailer and add MimeType=image/x-canon-cr2;.... to gdk-pixbuf-thumbnailer

Works great with *.cr2 files.

Can this add-on be included in the upstream? I checked on different files from three different cameras. I think problems should not be.
Comment 6 Bastien Nocera 2017-04-22 19:54:46 UTC 
ufraw needs to ship a ".thumbnailer" file which calls gdk-pibuxf-thumbnailer. See the similar commit for librsvg.
