My guess is that you are not correctly using the Parmetis provided by
PETSc, which I think is required by MUMPS.

Try configuring libmesh with

--with-metis=PETSc

and see if that fixes the issue...

Otherwise, you just have an invalid mesh.  You didn't say where it came
from, but if you made it yourself with a mesh generator, I would
double-check that it has correct connectivity, etc.
