I have fixed this bug. It did not come up in nightly tests because we are
not using MatSetValuesLocal(). Instead we
use MatSetValuesClosure() which translates differently.

Here is the branch

  https://bitbucket.org/petsc/petsc/branch/knepley/fix-dm-ltog-bs

and I have merged it to next. It will go to master in a day or two.

Normally we are faster, but the start of the semester was hard this year.

  Thanks,

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
