resque-scheduler fails on job remove

问题

I have used the POC from the Github (queue was missing to I have added it:

name = 'send_emails'
config = {}
config[:class] = 'SendEmail'
config[:args] = 'POC email subject'
config[:cron] = '* * * * * *'
config[:persist] = true
config[:queue] = 'new'
Resque.set_schedule(name, config)
sleep(10)
#Try to remove the job
Resque.remove_schedule(name)

I get the following error:

/var/lib/gems/1.9.1/gems/resque-scheduler-3.0.0/lib/resque/scheduler.rb:295:in `block in update_schedule': undefined method `keys' for nil:NilClass (NoMethodError)

This is a bug in rescue scheduler. When you remove the last job, the scheduler fails. The bug has been fixed in later releases. You can find complete details here
