Simple tobi usage results in exception

I am using node version v.0.5.11-pre with tobi 0.1.1 and the following simple sample

tobi = require('tobi');

browser = tobi.createBrowser(80, 'google.com', {external:true});

browser.get('/', function(res, $){  
});

results in exception

node_modules/tobi/lib/cookie/index.js:26
this.name = str.substr(0, str.indexOf('='));

TypeError: Object PREF=ID=f886a9c19ecc3d44:FF=0:TM=1320856926:LM=1320856926:S=Yw911ELXKPXLIKxO;

Any ideas?
