NoMethodError at /resque_admin/delayed undefined method `[]' for nil:NilClass

I can't see the delayed jobs page anymore.
That happened after removing a delayed job.
Some stacktrace:
NoMethodError - undefined method '[]' for nil:NilClass: /home/coorasse/.rvm/gems/ruby-1.9.3-p484/gems/resque-scheduler-2.4.0/lib/resque_scheduler/server.rb:137:in 'block (2 levels) in singletonclass' /home/coorasse/.rvm/gems/ruby-1.9.3-p484/gems/resque-scheduler-2.4.0/lib/resque_scheduler/server.rb:118:in 'each' /home/coorasse/.rvm/gems/ruby-1.9.3-p484/gems/resque-scheduler-2.4.0/lib/resque_scheduler/server.rb:118:in 'block in singletonclass' /home/coorasse/.rvm/gems/ruby-1.9.3-p484/gems/resque-scheduler-2.4.0/lib/resque_scheduler/server.rb:86:in 'instance_eval' /home/coorasse/.rvm/gems/ruby-1.9.3-p484/gems/resque-scheduler-2.4.0/lib/resque_scheduler/server.rb:86:in 'singletonclass' /home/coorasse/.rvm/gems/ruby-1.9.3-p484/gems/resque-scheduler-2.4.0/lib/resque_scheduler/server.rb:84:in '__tilt_6240240'

I solved only cleaning the Redis DB. Actually I can do that in development but not certainly in production!

Some mroe infos:
I added the job like that:
Resque.enqueue_at(TIME, ProposalsWorker, {:action => ProposalsWorker::ENDTIME, :proposal_id => @proposal.id})

and removed with
Resque.remove_delayed(ProposalsWorker, {:action => ProposalsWorker::ENDTIME, :proposal_id => @proposal.id})
