What version of Open MPI are you using?

We had a bug with this on the trunk and [unreleased] v1.2 branch; it was
just fixed within the last few hours in both places. It should not be a
problem in the released v1.1 series.

Can you confirm that you were using the OMPI trunk or the v1.2 branch? If
you're seeing this in the v1.1 series, then we need to look at this a bit
