My output from the same commands:

$ echo "defensive" | aspell -a
@(#) International Ispell Version 3.1.20 (but really Aspell 0.50.5)
& defensive 14 0: defencive, defensively, defence, defensible, tensive,
definitive, defenced, defences, detersive, deafens, defective, diffusive,
defencing, offencive

$ echo "defencive" | aspell -a

$ dpkg -l aspell aspell-en | grep ^ii

A friend of mine also experiences the same problem. Our locales are set to en_GB
