                ]
            }
        }

};

Тут и в документации на бем.инфо ошибка с тэгом img.

{
    block: 'icon',
    tag: 'img',
    attrs: { src: 'http://varya.me/online-shop-dummy/desktop.blocks/b-logo/b-logo.png' }
}

выдает: <i class="icon" src="blablabla"></i>

нужно заменить на:

{
    block: 'icon',
    content: {
        tag: 'img',
        attrs: { src: 'http://varya.me/online-shop-dummy/desktop.blocks/b-logo/b-logo.png' }
    }
}
