[firedrake] Concatenation of function spaces?

[Justin Chang]

Not sure if this is related, but I had to update my petsc4py to get this
branch to work. But now I am getting this error, even in PyOP2

Traceback (most recent call last):

Is this more a petsc4py error? As in should it be reported to the
petsc-users list?

Thanks,
Justin
