I think I've found the fix, and issued a PR:

https://bitbucket.org/yt_analysis/yt/pull-request/151/fixing-a-typo-that-only-exposed-itself

In summary, Matt successfully exposed a typo that only matters when
few MPI tasks "own" a halo, and when the root task doesn't own any
halos, which can happen when (number of MPI tasks) > (number of
haloes).
