Interesting real world short ID collision

[David Shaw]

As pointed out in Debian bug 659905, on the keyservers, the primary key 171CAA4A (dated 2002) collides (presumably naturally) with a subkey on primary key 1C8BB5A7 (dated 2000).

It seems the owner of one went to a keysigning party, and an attendee was rather surprised to find two keys coming back from the keyserver for that ID...
