event with price set blows up before taking fee. registered participants not showing up in reports.

I noticed that although we have had people sign up for an event, the event reports are showing no participants.

Wordpress 3.5.1 with Civi 4.3 B4.

The event now has both a fee and an upsale with a price set. When I went to sign up for the event, I got the following back trace:
