CVS commit by staikos: 

rvectors should not crash if they cannot find the file they need.  It's not
pretty, but I would rather have null files than have files that are useless
in all ways except that they are not null.  Meanwhile we shouldn't return
null files for dirfiles that don't exist yet.  That will be fixed next.
