I see that hotot is dead for a long time: http://hotot.org/this-project-has-been-discontinued/ Then, it won't likely even ported to new webkitgtk. As it requires an obsolete and vulnerable webkit-gtk slot, I would then suggest to disable its optional support (if you still want to keep this package in the tree) Thanks
