ngdoc.js, line 440, gruntUtil.getVersion().number is returning undefined:

if (this.section === 'api') {
  dom.tag('a', {
      href: 'http://github.com/angular/angular.js/tree/v' +
        gruntUtil.getVersion().number + '/' + self.file + '#L' + self.line,
      class: 'view-source btn btn-action' }, function(dom) {
    dom.tag('i', {class:'icon-zoom-in'}, ' ');
    dom.text(' View source');
  });
}
