  We give a number of examples of exotic actions of locally compact groups on
separable nuclear C*-algebras. In particular, we give examples of the
following:
  (1) Minimal effective actions of ${\mathbb{Z}}$ and $F_n$ on unital nonsimple
prime AF algebras.
  (2) For any second countable noncompact locally compact group, a minimal
effective action on a separable nuclear nonsimple prime C*-algebra.
  (3) For any amenable second countable noncompact locally compact group, a
minimal effective action on a separable nuclear nonsimple prime C*-algebra
(unital when the group is ${\mathbb{Z}}$ or ${\mathbb{R}}$) such that the
crossed product is $K \otimes {\mathcal{O}}_2$ (${\mathcal{O}}_2$ when the
group is ${\mathbb{Z}}$).
  (4) For any second countable locally compact abelian group which is not
discrete, an action on $K \otimes {\mathcal{O}}_2$ such that the crossed
product is a nonsimple prime C*-algebra.
  In most of these situations, we can specify the primitive ideal space of the
C*-algebra (of the crossed product in the last item) within a class of spaces.
