More MD5 Collisions

Bruce Schneier warns:

    Two researchers from the Institute for Cryptology and IT-Security have generated PostScript files with identical MD5-sums but entirely different (but meaningful!) content. (Other MD5 attacks are summarized here.)

Now this is something interesting. Until now all hash collisions were statistically insignificant. Previously any collisions were between two pieces of data: one was meaningful (legal contract, credit card number, etc.) and another that was gibberish.
