[Dune] Runtime error with parallel linear solver

[Tobias Ritschel]

Ah, this is clearly my error. I am using the constructor

OwnerOverlapCopyCommunication
<http://www.dune-project.org/doc/doxygen/dune-istl-html/class_dune_1_1_owner_overlap_copy_communication.html#a93f446939bd4d6623bdf2e544f183f8c>
(MPI_Comm
comm_, SolverCategory::Category
<http://www.dune-project.org/doc/doxygen/dune-istl-html/struct_dune_1_1_solver_category.html#ae061380ac961490be6ee353cf0dc1733>
cat_=SolverCategory::overlapping,
bool freecomm_=false)

and used the created object without an index set. Is the information
automatically set up when constructing an IndexInfoFromGrid object, or
should they be set with AddLocalIndex and AddRemoteIndex? And is this the
most convenient way to set up the indices?
