Bug Description

When converting a Gmsh-mesh with a mesh function using dolfin-xml with, e.g.,

$ dolfin-convert mymesh.msh mymesh.xml

"new style" XML-files should come out.
However, when trying to read in the generated file in parallel, the following error message appears

*** Error: Unable to read mesh function from XML file.
*** Reason: Reading old-style XML MeshFunctions is not supported in parallel. Consider using the new format.
*** Where: This error was encountered inside XMLMeshFunction.h.
*** Process: 0

This can be reproduced with the mesh at http://win.ua.ac.be/~nschloe/other/circles2d.msh and the Python lines

from dolfin import *
mesh = Mesh('circles2d.xml')
subdomains = MeshFunction('size_t', mesh, 'circles2d_physical_region.xml'
