Cannot install with bower

[retan]

Like the topic states. I cannot install this package with bower.
My last try (with clean cache) is:

bower install --save-dev git+https://github.com/helpers/handlebars-helpers

The result (some private directory names replaced with `xxx'):

Basically each time it crashes on different dependency.
Bower and node are updated. Windows 64bit Pro here.
