btrfs balance start worked a bit farther after apt-get clean and completed
after removing the one and only snapshot from 2013-05-01.

Still I consider this a bug.

Mount options:

martin@merkaba:~> grep "/ .*btrfs" /proc/mounts
/dev/mapper/merkaba-debian / btrfs rw,noatime,compress=lzo,ssd,space_cache 0 0

State after removing snapshot and balance:
