We had an entry for that, and there didn't seem to be anything wrong with it, yet mysteriously the warning remained. Nothing in the error message told us that the problem was with the "group" entry -- it should have said "the 'group' option for mysqld does not exist" or given some other kind of syntax error. We figured it out eventually, but it's not widely known that MySQL will try to expand options to what it *thinks* you meant.

Mysql told you there was something wrong with your configuration change, it's not their fault if you ignored it. I don't see how it's a bug, it sounds to me like user error. Why are you complaining?
