Exposed taxonomy term filter fine for "All", shows no results for specific term

I have a site where I originally set up using the date-browser view in calendar display mode to show the calendar. The client wanted to color entries on the menu based on taxonomy term, so I set out to set the calendar view up just as the date-browser view was set, but with the added color configs.

The "event" type is a CCK node with a date field in addition to body and title. Repeat dates are on. Location module connects a location to the event type. Nothing earth shattering. There is a single taxonomy with four peer level terms to classify events.

The date-browser view allows me to select single terms from the exposed taxonomy filter and properly filters the events.

The calendar view shows all of the events when the filter is set to All, and shows none of them when any other term is selected.

When I run the SQL that is produced by the view when a filter is applied, I get back the expected results in mysql.

This implies to me that something in the calendar module is not able to retrieve the results, or is electing not to display them.
