Hi,

I just noticed that the convergence of the PETSc Krylov solvers declined
rapidly since rev 4832 (before the big interface change). Attached are 2
runs of the same demo, for 4832 and 4863. The computed solution is
obviously the same. My guess is something is wrong with the
preconditioner. Or do I need to change any of the newly introduced
parameters (reuse_preconditioner, same_nonzero_pattern)?

Florian
