Just calling the "/answers" endpoint, no specific arguments, and I'm getting 500 errors:

http://api.stackexchange.com/2.0/answers?order=desc&sort=activity&site=gaming

 {"error_id":500,"error_name":"internal_error","error_message":"this error has been logged"}

I didn't notice this on StackOverflow, but MSO is doing the same thing as gaming is.
