Just try to clone that repo and call node index.js
You'll see an error just like this:
bobrik@server:~/****/node_modules/bug$ node index.js
Bug included! Running script

node.js:134
throw e; // process.nextTick error, or 'error' event on first tick

Open Admin.js
and comment out line 7 and everything goes well.
I suppose this is wrong behavior.
