I do get the citations, but not the references in Classicthesis.
Philip P (thanks for your help!) recommended to check the 'two simple
examples' in http://wiki.lyx.org/BibTeX/Biblatex with my debian setup,
one for bibtex, one for biber. The former produces both, the citations
and the Bibliography, the biber version only the citation. Here are the
logs (###A. for Bibtex, ###B. for Biber)
