URGENT : Problem in OMIM parser

I have downloaded the omim.txt file from NCBI ftp site and I am running my
attached parser on this file, the parser run stops in between with this :-

------------- EXCEPTION  -------------
MSG: a part/organism must be assigned
STACK Bio::Phenotype::OMIM::OMIMentry::add_clinical_symptoms
/usr/lib/perl5/site_perl/5.8.8/Bio/Phenotype/OMIM/OMIMentry.pm:566
