Created attachment 1303370 [details] Image that fails to load Description of problem: After updating to gdk-pixbuf2 2.36.7 eog is no longer able to open black and white jpeg images, erroring out with: "Unsupported number of color components (1)" when used on an image that file identifies as: JPEG image data, JFIF standard 1.02, aspect ratio, density 1x1, segment length 16, baseline, precision 8, 7746x6558, frames 1 a full colour image (with frames 3) displays correctly. An example image that fails to display is attached. Version-Release number of selected component (if applicable): gdk-pixbuf2-2.36.7-1.fc26.x86_64
Downgrading to gdk-pixbuf2-2.36.6-1.fc26.x86_64 fixes the problem.
This is already fixed upstream: https://bugzilla.gnome.org/show_bug.cgi?id=785171 I guess it needs to be backported.
Same issue with eog in Fedora 25
For F25, the upstream fix is still NOT included in gdk-pixbuf2 2.36.7-2.fc25 https://git.gnome.org/browse/gdk-pixbuf/commit/?id=6dd89e1
(In reply to Tom Hughes from comment #1) > Downgrading to gdk-pixbuf2-2.36.6-1.fc26.x86_64 fixes the problem. Installing gdk-pixbuf2-2.36.8-1.fc26 from koji (https://koji.fedoraproject.org/koji/packageinfo?packageID=10563) fixes it.
