Created attachment 299173 [details] screenshot of a bug with no email address set for needinfo
This is a bug from the Red Hat Hardware Catalog and is normally not edited from the normal Bugzilla UI. Having an empty requestee value for the needinfo? flag is a valid option and just means that whomever makes the next comment will put the bug back into the previous non-needinfo state. Dave
