Hi, Whilst working on the Reproducible Builds effort [0], we noticed that http-icons could not be built reproducibly. The GIF images were being optimised while building by converting to PNM and back to GIF. The conversion back to GIF introduced some variation. Upon further investigation, it looked like this "optimisation" was actually increasing the sizes of images (!), so I am just actually just dropping the optimisation here. :) Patch attached.
