I install MediaWiki v1.8.2 on MySQL v5.0.27 with 
option "Experimental MySQL 4.1/5.0 UTF-8" enabled and have error:

ERROR 1089 (HY000): Incorrect sub part key; the used key part isn't a string,
the used length is longer than the key part, or the storage engine doesn't
support unique sub keys

on query:
CREATE TABLE ipblocks (
...
  ipb_address varchar(40) binary NOT NULL default '',
...
  UNIQUE INDEX ipb_address (ipb_address(255), ipb_user, ipb_auto, ipb_anon_only),
...
)

Fix:
change maintenance/mysql5/tables.sql from
  UNIQUE INDEX ipb_address (ipb_address(255), ipb_user, ipb_auto, ipb_anon_only),
to
  UNIQUE INDEX ipb_address (ipb_address(40), ipb_user, ipb_auto, ipb_anon_only),
