400 bad request

[snacktime]

nginx doesn't log these errors for some reason.  They don't show up in the access or error log, and we have both turned on.  If I could look at the raw data I could figure out if it's facebook that's breaking a spec somewhere, or if it's an nginx bug.  We have narrowed it down to being specifically a cookie issue.  More specifically it's facebook connect that sets the cookies nginx bombs on.
