MOSS: Render Failed Error for Custom View

I recently created a custom view in MOSS with a column using the Checkbox (Yes/No) data type. The view was filtering on that column (is equal to Yes).

I later changed the data type to Choice and provided Yes and No values. The view failed to render and displayed the error:



I modified the view (the filter was changed to "is equal to 1") to change the filter to Yes again and that fixed the issue.

I've never seen the render error before, so here you have it.
