As Nick guessed, I think the problem is you have 'dna' (lower case)
in the LOCUS line, rather than 'DNA' (upper case). Where did this
file come from? e.g. What software tool or database made it?

http://www.ncbi.nlm.nih.gov/Sitemap/samplerecord#MoleculeTypeB

In any case, perhaps Biopython could check for 'dna' as well
(as some tools don't seem for obey this bit of the standard)?

Thanks
