#6 Error building the final PDF

It appears that there's an extra half-generated table cell:
javax.xml.transform.TransformerException: org.apache.fop.fo.ValidationException: file:/c:/resume/examples/example2-filtered.fo:247:39: Error(247/39): fo:table-cell is missing child elements.

Basically there's one line that starts up another <fo:table-cell ...> If I delete that line, everything generates nicely again. Annoying to hand fix every time, but I don't know where in the fo generation process it happens.
