webform_emails.excluded_components is type text and may not have a default value

I have this inconsistency with my database schema...

webform_emails.excluded_components is type text and may not have a default value

webform
o additional_validate: unexpected column in database
o additional_submit: unexpected column in database

This appeared when I updated to the 6.x-3.2 version. Is this related to to any previous posts, I've missed? There doesn't seem to be any problems thus far, but what should I do to get rid of this appearing in the status report?
