Users/getCompletion now returning invalid JSON (recently broke)

You stopped returning JSON like { "371200": {"nick_name": "athenagrey", ... }, ... } and are now returning invalid JSON like { 371200: {"nick_name":...

resulting in a syntax error, unexpected TNUMBER, expecting TSTRING for 371200.

This has been going on since 09:36, 2009-04-06. We can't see our friends anymore! Please fix this as soon as you can.
