btrfs receive fails for second snapshot

[Miguel Negrao]

See upstream bug report: https://bugzilla.kernel.org/show_bug.cgi?id=60081
Confirmed broken in
Btrfs v0.20-rc1, working on Btrfs v0.20-rc1-335-gf00dd83 (from git). Perhaps ubuntu's btrfs-tools package should pull upstream ?

Info from bug report above:

sudo btrfs subvolume create test
cd test
nano a.txt
cd ..
sudo btrfs subvolume snapshot -r test testBackup1
sudo btrfs send testBackup1 > '/media/miguel/btrfs_backup/file1'
cd test
nano b.txt
cd ..
sudo btrfs subvolume snapshot -r test testBackup2
sudo btrfs send -p testBackup1 testBackup2 > '/media/miguel/btrfs_backup/file2'
sudo btrfs receive '/media/miguel/btrfs_backup/testBtrfsBackups' <
'/media/miguel/btrfs_backup/file1'
sudo btrfs receive '/media/miguel/btrfs_backup/testBtrfsBackups' <
'/media/miguel/btrfs_backup/file2'

The last command gives the error:
ERROR: open testBtrfsBackups/testBackup1 failed. No such file or directory

But the subvolume is there:

miguel@miguel-MacBookPro:/media/miguel/btrfs_backup/testBtrfsBackups$ ls -l
total 0
drwxr-xr-x 1 miguel miguel 10 Jun 25 09:59 testBackup1

The files file1 and file2 created are attached in case someone want to try
doing the receive part.
