Turning on 'ladder' on server with competitions already existing creates 500 errors

Turning on 'ladder' on server with competitions already existing creates 500 errors when in admin area and clicking on a competition name.

this seems to be the case even for servers without competitions.

• setup server with ladder.
• create comp
• click on comp
• 500 error
