You might try updating your local Bioperl; I can retrieve it using
bioperl-live:

---------------------

use Bio::DB::GenBank;
use Bio::SeqIO;

my $fac = Bio::DB::GenBank->new();
my $seq = $fac->get_Seq_by_acc('XM_547879');
my $seqout = Bio::SeqIO->new(-fh    => \*STDOUT,
                             -format => 'genbank');
$seqout->write_seq($seq);
---------------------

Gets this sequence (truncated for brevity):

---------------------
