[Dune] Fwd: gmsh2dgf

[Oliver Sander]

Hi,
I don't know much about either dgf or the EXPERIMENTAL_GRID_EXTENSIONS.
It may well be that the gmshreader contains a bug (it was me who wrote parts
of it, after all :-) ) but to look into that we'd need a more precise
report of what's going wrong.
Best,
Oliver
