My German is not amazing, but it looks like that was just a German TV version that, for their own reasons probably, trimmed off a scant 45 seconds. They also re-ordered THX's arrest scene so that it makes no sense, for some reason. The site owner attributes it to an error in the master which ommitted a few seconds and mixed up the scene order for the arrest sequence, which may or may not be true--but either way, its less than a minute shorter overall. Another interesting variant, but not the droids we're looking for. Cool catch though!

EDIT

This does seem to lend further credence to my theory of regional variation. Because it seems totally re-editing the scene order of the arrest sequence is not just "an error" in the broadcast, but a deliberate manipulation.
