rvm & Vagrant : NoMethodError: undefined method `keys' for []:Array

[thecatwasnot]

I'm eventually trying to set up a vagrant box to be used as a dev workstation. I'm new to vagrant & chef but not new to linux or rvm.
For the moment I'd just be happy to get a vagrant box running with rvm. I think I've got rvm configured the way I want in my Vagrantfile, but running it produces the above error. I'm fairly sure this is a user error, I haven't understood or configured something correctly but digging into the code that produced the stacktrace hasn't produced anything useful for me.
I've gisted my Vagrantfile & the full stacktrace that chef-solo produces.

I think this is due to a documentation/usage error. I added a comment to the gist which should hopefully get it rolling. If it doesn't, then please keep this issue alive :)

That did it, thanks!
