It might be triggered by PETSc in some subtle way, but I'm certain now
it's not being caused by PETSc - we've got a corrupt entry being
generated at the end of the send_list.

Still need to figure out how.  If you haven't triggered it, and I
can't trigger it with any CG work, then my best guess is that I typoed
Lorenzo's latest DG send_list patch when integrating that recently.
