Sub Articulo 117.0

 I manage my references with BibTeX together with the
harvard.sty-package. Whenever I try to use a command provided by this
package in a headline, I get an error message. For example
\section{\citeasnoun{Pfann:89}}
produces
! Argument of \@sect has an extra }.

                \par
l.42 \section{\citeasnoun{Pfann:89}}
