The original report can be found here:

The reproducer for this issue is:

truncate -s 10GB pool.btrfs
mkfs.btrfs pool.btrfs
mount -t btrfs pool.btrfs /mnt
btrfs subvolume create /mnt/a
btrfs subvolume snapshot /mnt/a /mnt/snap-a
btrfs send /mnt/snap-a | btrfs receive /mnt/a

should incorrectly fail with

ERROR: empty stream is not considered valid

whereas it should actually succeed. I've pushed a patch
for this to btrfs upstream (https://bugzilla.kernel.org/attachment.cgi?id=256157)
which is already merged. We should SRU it.
