Right, but if this were the case shouldn't converting from a simple  
format (one lacking most annotation and feature information,  
including a source, like fasta) to genbank raise all sorts of  
warnings?  I get this conversion to work without errors or warnings,  
though there doesn't seem to be any attempt by SeqIO to check the  
fasta header line for accessions, etc. (a separate issue which I  
think Jason mentioned a fix for; I guess it hasn't been implemented  
yet).  No source line is in the output sequence either.
