Rails - Nov 2005 - AR optimistic locking error when not using #attributes= ?

Hello all,
 Please review this script/console output (using Login Generator modified) :
 >> users = User.find(:all, :limit=>10)
=> [...]
 >> users.each do |user|
?> user.password = user.password_orig
>> user.password_confirmation = user.password_orig
>> user.save
>> end

  Why is AR buying day-old bread when the object is updated on separate
lines ?
 Is this a bug I should be reporting ?
