I'm having a runtime errror when i'm looking at the "workers" tab on resque-web (localhost). Everything else works.

Edit: when this error occurs, i also have some (3 or 4) unknown workers 'not working'. I think they are responsible for the error but i don't understand how they got here

Can you help me on this ? Did i do something wrong ?
