   @dhardtke I found a solution by change the raphael.json.js, do not use matrix.toTransformString(), use el.transform().toString():

   (function () {
       Raphael.fn.toJSON = function (callback) {
           var data, elements = new Array, paper = this ;
   
           for (var el = paper.bottom; el != null; el = el.next) {
               data = callback ? callback(el, new Object) : new Object;
   
               if (data) elements.push({
                   data: data,
                   type: el.type,
                   attrs: el.attrs,
   //              transform: el.matrix.toTransformString(),
                   transform: el.transform().toString(),
                   id: el.id
               });
           }
   
           var cache = [];
           var o = JSON.stringify(elements, function (key, value) {
               //http://stackoverflow.com/a/11616993/400048
               if (typeof value === 'object' && value !== null) {
                   if (cache.indexOf(value) !== -1) {
                       // Circular reference found, discard key
                       return;
                   }
                   // Store value in our collection
                   cache.push(value);
               }
               return value;
           });
           cache = null;
           return o;
       }
   
       Raphael.fn.fromJSON = function (json, callback) {
           var el, paper = this ;
   
           if (typeof json === 'string') json = JSON.parse(json);
   
           for (var i in json) {
               if (json.hasOwnProperty(i)) {
   
                   el = paper[json[i].type]().attr(json[i].attrs);
                   if (json[i].transform != null) {
                       el.transform(json[i].transform);
                   }
   
                   el.id = json[i].id;
   
                   if (callback) el = callback(el, json[i].data);
   
   //              if ( el ) paper.set().push(el);
               }
           }
       }
   })();

   Maybe you should fork raphael.json and create a pull request for this? :)
