Please have a look on this.

Based on a little research, I think the problem here is either an old version of asciidoc or the Docbook XSL stylesheets not being available locally and remote connections being either denied or very latent. It probably isn't an issue with the Icecream codebase. Please try looking into the potential issues I've mentioned to see if changing one of them fixes your problem.
