Could you try this with the integration branch of the btrfs tools, available from: http://git.darksatanic.net/repo/btrfs-progs-unstable.git/ in the "integration-20110703" branch. There's a patch in there that should deal with this particular problem (if it's what I think it is, which it probably is).
