commit aa7fe6ce25205c34b2cc9cd56650c6eba752255a
Author: Lars Ingebrigtsen <larsi@gnus.org>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Don't message complete GIF data upon errors
    
    * src/image.c (gif_load): When unable to parse a GIF specified
    via a data attribute, don't message the complete binary, because
    that's not useful (bug#40850).
