```Dear List,

I have a horrible feeling that this is something that might be an FAQ,
but I can't see an answer to it if so despite Googling.

I'm getting a couple of errors like

LaTeX Warning: Label `cbx at 4' multiply defined.

I assume from the cbx that this might have something to do with
biblatex, but does anyone have any thoughts on how best to track down
the error?

Best wishes,

Nicholas
