This could be a FFC bug. For the Poisson DG example, looking at the 
generated contents of

    bool ufc::dof_map::needs_mesh_entities(unsigned int d) const

I see

   switch ( d )
      {
      case 0:
        return false;
        break;
      case 1:
        return false;
        break;
      case 2:
        return true;
        break;
      }

Shouldn't 'case 1' also return true (that is, cell edges are required)?
