Details - Since the dune-grid r7664 I get a segmentation fault using the gridptr with UG in parallel like this:
   
Dune::GridPtr<Dune::UGGrid<3> > gridptrug(string, helper.getCommunicator() );

The problem can be seen in the testug example in dune-grid/dune/grid/io/file/dgfparser/test, running it like this:
mpirun -np 2 ./testug

I updated and recompiled dune-grid, if I switch back to revision 7663 everything works fine.
