Yes, the key length is critical. It's because of the ability to vary
the key length that this attack is possible. MD5 is a hash, and there
are an infinite number of sequences that will generate any particular
MD5 identifier. Obviously we are limited to throwing our much much
much smaller than "infinetly large" keys, but even within the range of
those keys acceptable to pgp there are ways to generate collisions.
