When running 'make runtests' on the latest dev versions of everything
I get lots of failed tests and demos failing to converge.

Some selected shortened examples with 6 different errors, most of
these occur multiple times:


----------------------------------------------------------------------
Running C++ demo ./../../demo/pde/biharmonic/cpp
Solving linear variational problem.
terminate called after throwing an instance of 'std::runtime_error'
  what():  *** Error: PETSc Krylov solver did not converge in 10000
iterations (PETSc reason DIVERGED_ITS, norm 1.954526e-01).


----------------------------------------------------------------------
Running C++ demo ./../../demo/pde/cahn-hilliard/cpp
*** -------------------------------------------------------------------------
*** Error:  Unable to solve linear system.
*** Reason: Preconditioner may not be specified for LU solver.
*** Where:  This error was encountered inside LinearSolver.cpp.
