[NTG-context] bib module fails to produce publication list under certain conditions

I recently came across an unusual error with the bib module: depending on the section structure of a document, the publication list is sometimes not produced. I've attached a simple document and a one-entry bib file that illustrates the error. If either the second section of the subsection is commented out, the publication list is produced; if both are uncommented, the publication list is not produced. What might be going on?
