I also get the same behavior on my laptop so it is not just the buildbot:

[1]PETSC ERROR: --------------------- Error Message
------------------------------------
[1]PETSC ERROR: Nonconforming object sizes!
[1]PETSC ERROR: Sum of local lengths 565 does not equal global length
564, my local length 282
  likely a call to VecSetSizes() or MatSetSizes() is wrong.
See http://www.mcs.anl.gov/petsc/petsc-as/documentation/troubleshooting.html#PetscSplitOwnership!

(This time PETSc was configured with SPOOLES instead of MUMPS.)

What is also strange is that the corresponding Python demo
(demo/pde/poisson/python) is working very nicely.
