bug#17866: 24.3; Movement in buffer *image-dired* sometimes is impossible

[marcowahlsoft]

Do 'M-x image-dired' on a directory with some images.

$ ls
img_0.jpg
IMG_1418.jpg
IMG_1420.jpg
img_1.jpg
img_2.jpg
python-logo.png

Movement from one image to another (using e.g. SPC) fails.

This report goes back to the post of Steven Arntson:
