I'm running openSUSE 12.3 x86_64 which has an unknown git version, but
reports v0.19.
I'm also supplying the output from git which reports itself as:
v0.20-rc1-253-g7854c8b
The problem is that btrfs-show (git) and btrfs fi show (git) give
/different/ output from each other which is also different from the
(older) btrfs.
First btrfs-show (git):

Now btrfs fi show (git):

Btrfs v0.20-rc1-253-g7854c8b
And now the (older) btrfs fi show:
failed to read /dev/sr0
Label: none uuid: 7feedf1e-9711-4900-af9c-92738ea8aace

devid 3 size 460.76GB used 444.23GB path /dev/sda3
Btrfs v0.19+
which has similar output to the (older) btrfs-show.
The differences are:
1. the order of devices varies (not a big deal)
2. the current git btrfs-show and btrfs fi show both output
*different* devices for device with UUID
b5dc52bd-21bf-4173-8049-d54d88c82240, and they're both wrong.
Somewhat confusingly, /dev/disk/by-uuid/ only shows three devices:
bd40cb4e-93bb-4600-8455-ca1185aa8abe -> ../../md3
7feedf1e-9711-4900-af9c-92738ea8aace -> ../../sda3
4f0b27a5-5f5b-413c-a71b-b5a3bec5482c -> ../../md2
What's going on with the varied output from (git) btrfs-show vs.
'btrfs fi show' (vs. the older, as-shipped btrfs)?
