There are two problems:

1) The classes derived from SdrObject cache their SvxShape, but do not
   implement impl_setUnoShape().

2) There is a lifetime issue in association of a SdrObject and its
   SvxShape. SvxDrawPage::CreateSdrObject not only creates a new SdrObject
   for a shape, but also inserts it into the page. At this point, the shape
   has not been attached to the object yet. That means that the object
   creates another shape at one point during the InsertObject call,
   which is then destroyed again. But reportdesign shapes own their
   objects, which means that destuction of the shape causes destruction
   of the object too...

   My first idea was to disable the insertion in
   SvxDrawPage::CreateSdrObject, but it has been there since the dawn of
   time, so I did not gather the courage to do that. Instead, I put in a
   hack to allow to skip the insertion.
