One of my dependency folders is not copied from the bower dir to targetDir

[plato-cambrian]

grunt-bower-task@0.4.0 , grunt@0.4.5

I am writing a grunt-init script that assembles a scaffold for a material design component. It's a two step process:

First, run the grunt-init script to copy some scaffold content and generate src/bower.json, src/package.json, and src/Gruntfile.js in the current working directory.

Second, run grunt on this newly generated gruntfile. It contains a grunt-bower-task to install the component's bower dependencies into component/bower_components.

The package.json has a 'script':{'postinstall': 'grunt'}.
Thus, I should be able to have all my dependencies sorted after:

$ cd working-directory
$ grunt-init sopro-component
$ cd src; npm install

As you can see from the snippets below, I expect to see my sopro-material folder in component/bower_components after the grunt script runs.

What actually happens is, every other bower dependency is correctly copied there, but the sopro-material folder is not!

The folder DOES appear in the bower directory next to the bower.json file (not the target directory), e.g. src/bower_components/sopro-material

Please let me know if you can reproduce this or identify my problem!
