Jobs without payload are ignored

It's probably some weird edge case problem caused by resque backends dieing  unexpectedly. I'm unsure.
All I know is that this fixed the problem on our server: it allowed me to list & restart failed jobs which were otherwise inaccessible due to code of this type raising an error:

  job["payload"]["class"] # => raise no method [] for nil

So there were blank jobs or jobs without payload. Pre-selecting fixes the immediate problem.
