  We study integrability for coactions of locally compact groups. For abelian
groups, this corresponds to integrability of the associated action of the
Pontrjagin dual group. The theory of integrable group actions has been
previously studied by Ruy Exel, Ralf Meyer and Marc Rieffel. Our goal is to
study the close relationship between integrable group coactions and Fell
bundles. As a main result, we prove that dual coactions on C*-algebras of Fell
bundles are integrable, generalizing results by Ruy Exel for abelian groups.
