Details - The documentation of

Dune::Preconditioner< X, Y >::apply (X& v, const Y&d) 	

specifies that on exit v=M^{-1}d. This, however, is not implemented as such - at least in the Jacobi Preconditioner SeqJac. If v already contains old data it is not overwritten but used in the dbjac method.

I would therefore suggest either adjusting documentation or setting v=0.0; in the beginning of apply(v,d) to match the documentation/specification.
