gdk-pixbuf-thumbnailer fails to create thumbnails for CR2 100% of the time.
I have been adding image/x-xpixmap;image/x-canon-cr2;image/x-adobe-dng
to the end of the line starting with MimeType=
in the file /usr/share/thumbnailers/gdk-pixbuf-thumbnailer.thumbnailer
since Ubuntu 18.10 for the thumbnailer to create the thumbnails primarily for the ".CR2" raw files from my Canon 77D and 80D cameras.
Unfortunately I have to report that as of Ubuntu 19.10 this solution doesn’t work on my machine anymore. The thumbnailer tries to create the thumbnails for .CR2 but fails and instead creates 1 pixel png images that it all puts in ~/.cache/thumbnails/fail/gnome-thumbnail-factory
. This is a pretty big deal for me since I have tens of thousands or CR2 photos.
Is there any solution? Should I test something? If yes then what/how? Any help is greatly appreciated.
I've also created a bug report on launchpad: https://bugs.launchpad.net/ubuntu/+source/gdk-pixbuf/+bug/1863797
I've attached a CR2 photo of mine that anyone can use for testing.IMG_1716.CR2
