Tests fail with a number or errors and warnings

[nfriedly]

Hi, I started working on a MongoDB plugin based off of this one, and I kept getting strange test failures, so it occurred to me to run the tests on this plugin, and sure enough, they're failing too:

$ cake test
cake compile
cake install
npm install (for app)
npm install (for test)
npm install (for docpad tests)
coffee compile
npm test

> docpad-plugin-tumblr@2.0.6 test c:\Users\IBM_ADMIN\Downloads\docpad-plugin-tumblr-master
> node ./out/tumblr.test.js

tumblr-master
tumblr-master > create

In my case, I'm getting a somewhat different set of errors (http://stackoverflow.com/questions/26391988/docpad-plugin-odd-errors-when-testing-hangs-when-including-in-project) but it does still have the Error: Didn't place the skeleton as the desired structure already exists one - any idea what's going on here?

I fixed my plugin - the main thing that was getting me was that TaskGroup doesn't ever fire the .once('complete', callback) event - at least not the current version. Changing it to .done(callback) was enough to make my project work.

However when change that in my fork of this and run the tests, it still fails with similar output to above. I'm using the git bash shell on windows 7, so maybe that makes the environment properties behave differently (?)
