(Sorry, I completely forgot about that. Will do in the future)

I tested it with the latest version of feh and can reproduce the issue.

However, the problem is caused by imlib_load_image_with_error_return
(or, more specifically, the load function in Imlib2's gif library), which is
out of feh's scope. Since the image also causes a segmentation fault in sxiv
(another imlib2 based image viewer), I think the bug report should be moved to
the Imlib2 package.
