MultiValue profile properties

The problem is that you can't set a Profile["ProfileSystem.multivalueproperty"] = null or object[]{} to represent an empty array. When you try to set it to null it appears to work but even after a Profile.Update() the profile remains unchanged and the array remains full. If you try to set it to an empty array the MembershipProvider errors out and tells you that you have sent invalid data. The UpmMembershipProvider tries to set the logon_error_dates = null in its EraseFailedLoginHistory method. That's why the logon error dates field is unable to be nulled out. I'm pretty sure that this worked fine pre SP1. It looks like Microsoft broke their own UpmMembershipProvider in SP1. If we can get a hotfix for this it would be great as I am waiting on this to launch our site.
