/.../deal.II/source/fe/fe_values.cc(430): warning #327: NULL reference is not allowed

      fe_values(*static_cast<dealii::FEValuesBase<dim, spacedim>*> (0)),
                ^
          detected during instantiation of "dealii::FEValuesViews::Tensor<2, dim, spacedim>::Tensor() [with dim=1, spacedim=1]" at line 76 of "/usr/include/c++/4.6/bits/stl_construct.h"

But we'd like to use this construct anyway.
