Now it's working. I added the vectors I mentioned before to the system using
the routine System::add_vector() and the cg works after the

Could you help me out with the preconditioners please?
You're using PETSc? Try
-pc_type bjacobi -sub_pc_type ilu -sub_pc_factor_levels 4
-sub_pc_factor_zeropivot 0
on your program's command line.
