It's a LaTeX one, or rather a BST one and you need to look at the BST what it shows there.
Eberhard, It's either LaTeX or JabRef changing how it presents the bibtex entry to lyx.
Look for something like (from another style): FUNCTION {emphasize} { duplicate$ empty$ { pop$ "" } { "\emph{" swap$ * "}" * } if$ }
It's not the emphasis as nothing in the document is emphasized; the error appeared only after I added that one citation and the reference was added to the bibliography.
but search for the old ones, of course, ie \bf, \sc and so on...
I grep'd the .lyx file for those strings and found none. Thanks, Rich
