When does this occur?
1. Creating a user through the control panel using Membership Administration (requires administrative privileges)
2. Could occur if a custom plugin was deployed that copied off the extended attributes on a create user event and in turn re-saved those attributes using the UpdateUser API (this is unlikely, but possible)
If you have any questions or would like assistance with applying the patch, please contact support.
