Robert is rith in #6, here is what I did on my system to get rid of the snapshots:
mount /dev/sda1 /mnt/tmp #Mounted the same volume for the second time on a running system, can be done online
cd /mnt/tmp
btrfs subvolume list /mnt/tmp/
btrfs subvolume delete /mnt/tmp/@apt-snapshot-2013-01-01_12:42:41/@
btrfs subvolume delete /mnt/tmp/@apt-snapshot-2013-01-01_12:42:41

and repeated for all the other snapshots which would not disappear
