If I solve the mass matrix without applying Dirichlet bc, then there is 
now problem. But, when I apply Dirichlet/Slip bc and then solve it 
crashes. However before the last upgrade there was no problem.

I check again now: I have dolfin from one month before: everything works 
but Lu.factorize;
I upgraded dolfin couple of days ago: hypre does not work for the mass 
matrix after applying dirichlet bc, and lu.factorize still does not work.


I am checking now for poisson.
