Which means the probability of generating a hash value of the form 0[eE][0-9]{30} is (1/128)(10/16)^30 or 5.9e-9.
It certainly reduces the strength of the hash (and MD5 shouldn't be used anymore in any case), but still a roughly 6 in a billion chance of someone choosing e.g. a password and it happening to be exploitable in this manner.
