The python LA unit test desperately need a revamp... We have removed the 
Matrix slicing as it is broken in parallel and the present Matrix test more or 
less just test the slicing.

However feel free to add more test classes. For example one could be specific 
for testing parallel stuff. Something like:

class ParallelStuff(obejct):
    pass

...

if has_la_backend("PETSc"):
    bases = (AbstractBaseTest, DataNotWorkingTester,\   
             unittest.TestCase)
    bases += (ParallelStuff,) if MPI.num_processes()>1 ()
    PETScTester = type("PETScTester", bases, {"backend":"PETSc"})

Bug description:
  The size of vectors resized through PETScMatrix::resize is wrong for
  non-square matrices. The left and right matrices are switched. Patch
  attached.
