Interesting... I tried this on three machines Windows/Python 2.4.3,
FC4/Python 2.4.3, Ubuntu/Python 2.5.1 and I saw the same thing for each...
It's apparently not a three character issue but rather related to specific
characters (e, n, o, r, t). A further test revealed that this affects one
additional character... the . (period/dot) character.

Here's what I did to test it:

for i in range(97,123):
 x = 'ab' + chr(i) + '.torrent'
 y = x.rstrip('.torrent')
 print ('Before: %s (%d)\tAfter: %s (%d)' % (x, len(x), y, len(y) ) )
