Ulrike,
at a first glance is seems that \filbreak is the best solution because
one could consider to redefine the section command:

  \newcommand\Section[1]{\section{#1}\filbreak}

It works like a charm if the paragraph fits on the current page, but
unfortunately it's moved to the next page if there isn't enough space
on the current page.  See the example below.  However, it's good that
you mentioned it though.  It seems that \clearpage is the right way to
go for the time being.

Regards,
  Reinhard
