Game Rating Error

I'm getting 500 Internal Server errors querying the game ratings, for example

http://api.giantbomb.com/game_rating/2/?api_key=<mykey>&format=json

All other queries seem to work ok.  Also if I query a rating that doesn't exist, it properly returns 0 results.

I experimented with the field list, and determined that the problem is the site_detail_url field.
Append the following to the end of all game_rating and game_ratings queries to include all fields except for site_detail_url:

&field_list=api_detail_url,id,image,name,rating_board

I'll take a look at this after we get the redesign out.
