in application.js.php 
change line 90 from:
return t.apply([record.get('icon'), value.replace(/[\u00A0-\u9999<>\&]/gim, function(i) {    return '&#'+i.charCodeAt(0)+';';})] );return t.apply([record.get('icon'), value.toString().replace(/[\u00A0-\u9999<>\&]/gim, function(i) {    return '&#'+i.charCodeAt(0)+';';})] );
	that will force value to be a string
