Beamer with Biblatex: Bibliography entry font change has no effect

Question

I am using biblatex with bibtex backend in conjunction with beamer latex. When I set the color, for instance, bibliography entry title with

\setbeamercolor{bibliography entry title}{fg=green}

then the title is rendered in green, as expected. However, when I use

\setbeamerfont{bibliography entry title}{shape=\scshape,size=\tiny}

or any other font property, like family=\ttfamily, nothing happens.

The setup for beamer and biblatex is as follows:

\PassOptionsToPackage{pdftex}{graphicx} % pdftex hack fuer graphicx
\documentclass[pdftex,hyperref=pdftex,10pt]{beamer}
\usetheme{tw} % our special theme
\usepackage[style=authoryear,citestyle=alphabetic,backend=bibtex]{biblatex}
\addbibresource{references.bib}

[...]

\begin{frame}[t,allowframebreaks]{References}
  \frametitle{\bibname}
  \printbibliography
\end{frame}

Hope someone can provide some insight into this mess. Thanks Reiner

Actually you are simply lucky that the \setbeamercolor does anything useful. beamer hooks in the \newblock command and this will in most cases not work with biblatex but only with manual bibliographies. Use the biblatex tools like e.g. \DeclareFieldFormat{title}{{\scshape\tiny #1}}
