Er, not so. This just popped up again in a different doc without a
bibliography. But, a second ctrl-h to copy the whole error log produced the
.pdf.

With the first doc, a new ctrl-h also resulted in the .pdf being produced.

I'd still like to understand the error, but since I can send these docs to
my client there's no rush.
