Enqueue fails / Conflict with redis_namespace 1.3.1

[ticktricktrack]

With resque-loner 1.2.1 and redis-namespace 1.3.1 I get an error when enqueueing jobs. On every job, every class, no matter if resque-loner is actually being used or not.

I created a minimized example to test this at: https://github.com/ticktricktrack/resque_loner_namespace_conflict

With redis-namespace 1.3.0 things works fine.

See resque/redis-namespace#65. This is a redis version / redis-namespace version issue and not a resque-loner issue.
