Minimized example for conflict between resque_loner and redis-namespace

With resque_loner (1.2.1) and redis-namespace (1.3.1) I get errors whenever I try to enqueue any jobs. Does not happen with redis-namespace 1.3.0

Issue on redis-namespace

To reproduce the failure either run

rake spec
##or
rails console
Resque.enqueue(Dummy)
