No. I mean this one*:
http://www.dcs.ex.ac.uk/~aba/crypto-papers/dobbertin.ps
It's 2 pages and it's title is `Cryptanalysis of MD5 compress' dated
May 2nd 1996.
However it is most uninformative about _how_ he constructed the
collision, and how large a subset of states it would work for, and
cost functions for the subset(s) it applies to. (Only quantative
statement in the entire document is `the above collision took 10 hours
on a pentium').
