No, I tracked down the problem: the Fedora 19 GnuTLS documenation package omits /usr/share/info/gnutls-layers.png, i.e., it's a packaging error for that distro. I suppose this is another reason our documentation should have alternative text for each image that conveys technical information. ASCII art is one approach, but for the blind it's better to have a textual summary than to have ASCII art. (Ubuntu 13.04 (derived from Debian) does package the image, but it doesn't package the info files, just HTML.) While we're on the topic of images, we should prefer SVG to PNG for diagrams, as SVG scales better.
