Thanks, Ihor. That found it.

The bibtex entry had:

author = {BIS},

Change to:

author = {{Bank for International Settlements}},

and it all works a treat.

A short random test shows that the export chokes when there is a single name for an author. Again an example:

author = {{Wolfsberg Group}} works fine;

author = {{Wolfsberg}} chokes.

Thanks to you and to Bruce for the help.

Cheers,

Alan

Run M-x toggle-debug-on-error and then try to trigger the error. Then,
you will be able to see the whole backtrace and potentially find out the
problematic BiBTeX entry. If backtrace does not help, you may need to
use M-x debug-on-entry and use debugger (See 19.1 The Lisp Debugger in
Elisp manual).
