Using RC~1 and today RC-2 with Multiple bibliographies per section set, I get a LyX warning that there are undefined citations in all but the first section. Looking at the LaTeX log, I find:
Package natbib Warning: There were undefined citations. Package bibtopic Warning: Please (re)run BibTeX on the file(s): (bibtopic) Vol_25_1.2 (bibtopic) Vol_25_1.3 (bibtopic) Vol_25_1.4 (bibtopic) and after that rerun LaTeX.
