hello!

i observed some strange behavior when i run the periodic poisson demo
(/pde/periodic). i use PETSC as backend and when it comes to applying
the bc's i get strange messages all over std output, here is a cut-out
from that:

and and and...

this stuff occurs exactly between the "Applying periodic boundary
conditions" and the "Applying periodic boundary conditions (finished)"
and then the program finishes successfully, though i do not trust the
solution.
Do you ever had something similar to this?
Is there a problem that i can not use periodic boundary conditions
together with PETSC or did i possibly miss-configured either PETSC or
dolfin?


Thanks for your help,

Patrick
