(Python) dolfin crashes when trying to access <class 'dolfin.cpp.PETScMatrix'>.size(n) with wrong index n

Dear dolfin/fenics team,

I expect the following error should be caught when triggered from the Python interface?

Best wishes,

Hans

from dolfin import PETScMatrix
J=PETScMatrix()
J.size(0) #is 0
J.size(1) #is 0
J.size(2) #results in following:

python: /build/buildd/dolfin-1.0-beta2/dolfin/la/PETScBaseMatrix.cpp:33: dolfin::uint dolfin::PETScBaseMatrix::size(dolfin::uint) const: Assertion `dim <= 1' failed.
