Description

Since dune-common trunk@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@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:
