Is there an error type? This looks like just a stack trace, but
doesn't PETSc also let you know what assertion or signal killed you?

Is this related to the MPI issue from I was having earlier? Does
libMesh not work with the --disable-mpi option? Am I turning off
mpi correctly when I reconfigure PETSc?
We've got libMesh with --disable-mpi passing continuous integration
tests now, and all we do there is --with-mpi=0 for PETSc... This
certainly *looks* like some kind of MPI issue, though!
