Created attachment 1090800 [details] Badly generated thumbnail with default settings Description of problem: In my case, Canon CR2 RAW files get unusable thumbnails generated. Version-Release number of selected component (if applicable): $ rpm -q raw-thumbnailer raw-thumbnailer-3.0.0-7.fc23.x86_64 How reproducible: Always. Steps to Reproduce: 1. sudo dnf install raw-thumbnailer 2. navigate in Nautilus to folder with Canon CR2 (or any) RAW file Actual results: Thumbnails correspond to full image contents. Expected results: Thumbnails are sort-of grey and useless. Additional info: I found this fork which fixes the issue (in Ubuntu): https://github.com/angryziber/gnome-raw-thumbnailer and changing: Exec=/usr/bin/raw-thumbnailer -s %s %u %o to: Exec=/usr/bin/raw-thumbnailer -s 160 %u %o in: /usr/share/thumbnailers/raw.thumbnailer actually solves the problem as thumbnails get generated correctly. Please, fix/backport.

This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Issue is still present with raw-thumbnailer-3.0.0-8.fc24.x86_64, re-assigning. Going to test F25 shortly.
I have just updated libopenraw to 0.1.0 in rawhide, which includes a few CR2-related fixes. Could you check if rawhide packages fix the issue? If they cannot be installed on F25 without too much dependency hell, please let me know and I will check if I can make f25-specific packages available.
