Can you reproduce this with an upstream kernel, specifically from btrfs-next git://git.kernel.org/pub/scm/linux/kernel/git/josef/btrfs-next.git ? I will try and reproduce once I'm done working on the bug I'm currently working on in case you don't get to it before I do.
If you can still reproduce this please file a bugzilla at bugzilla.kernel.org and set the component to btrfs.
