Hey, Mike, that's this bit from MDC.pm:

     if(exists $MDC_HASH{$key}) {
         return $MDC_HASH{$key};
     } else {
         return "[undef]";
     }

Do you remember the rationale for returning a string instead of just 
undef?  Maybe we should at least make that configurable?  What do you think?
