That was a deliberate mistake to test your understanding (joke).  I'm
pleased you worked out what was wrong!

I put that line in to speed up my testing - and forgot to remove it.
Basically that line was to just return a dummy SeqRecord with an empty
sequence for the "coded_by" cases, rather than going online wasting
the NCBI server time.  With hindsight I could have edited my example
GenBank file to focus on the cases of interest.  Does that make sense?

Sorry for the confusion,

Peter
