Rackspace driver

[Cristovao Jose Domingues Cordeiro]

Hello,

is the Rackspace driver working properly? Because I am trying to boot instances 
through a Deltacloud cloud server which is connected to the Rackspace cloud and 
I am not succeeding.
Error message:
    NoMethodError - undefined method `unpack' for nil:NilClass

Thanks

Best regards,
