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?

Thanks,

Jesse
