Note that this *usually* indicates an error in the INI file. Perhaps
we should have better error checking/reporting for this case...

Can you send your ini file?

This should not be necessary; we all run MTT with the Specify::Simple

These results are reported to the central OMPI MTT database where we
get e-mail reports each morning.

This particular failure is a known issue; I believe there's a trac
