ValueError: No records found in handle

Hi Hugo,

Getting an error here is good - there were no GenBank formatted records
in your file (while there should have been an XML record). Perhaps if
we expect this to be a common error a more specific exception would
be nicer? e.g. ValueError("This is XML, not GenBank plain text")

Maybe I don't understand what you are querying?

Peter
