I just figured out what the problem was. The pictures were read-only (since I copied them from a CD), and feh was silently failing when trying to rotate the image.
Making the pictures writable solved the problem, but it would have been nice if feh had given some kind of indication as to why it failed (or perhaps even disable the options that don't work when the picture is read-only).
I will try to update the bug report to reflect this.
