The img2pdf autopkgtest has found a regression in Pillow. Minimal reproducer with the attached gif: python3 -c 'from PIL import Image;img=Image.open("animation.gif");img.seek(1);print(img.mode)' With 9.0.0 this will output "RGB" even though frame 1 is a palette based image. With Pillow 8.4.0 above one-liner will correctly print "P". I tracked this down to this commit: b383a175be70da0df33babea3d480efd9768e937 Thanks! cheers, josch
