Details - Since dune-common trunk at 6366 certain parts of the gmsh-reader fail to
compile.  It appears the boundary segments are instanciated with a dimension
not matching the grid.  dune-common at 6366 started prohibiting certain automatic
conversions (such as FieldVector<K, 2> to FieldVector<K, 3>), so compilation
fails now.  This was not a problem previously, because the offending code was
compiled but probably never executed.

One way to trigger the problem is to compile any of the 2D gridinfo-gmsh
utilities in dune-grid.  The error message looks like this:
