Localization page error (mysql user privilege error)

When accessing /civicrm/admin/setting/localization?reset=1
I get a :
DB Error: a515ac9c2796ca0e23adbe92c68fc9fc = 'unknown error', a515ac9c2796ca0e23adbe92c68fc9fc = null, 16 = null, Array = null, CREATE TRIGGER civicrm_domain_trigger BEFORE INSERT ON civicrm_domain FOR EACH ROW BEGIN END [nativecode=1227 ** Access denied; you need the SUPER privilege for this operation] = null

Not sure why you create a trigger in this page, but it seems that the already quite liberal "grant all on civicrm.* to civiuser@localhhost identified by 'whatever',"
it isn't good enough to be able to work

I have created the trigger by hand (with the super user root), and still this error.
