Error when trying to assign group manager priveleges

When I assign administrative priveleges to a user within a group, I can successfully grant that user the administrator role, but I get the following error message:
Notice: Undefined index: phase in views_handler_field->render_text() (line 1089 of /srv/www/julio/html/profiles/julio/modules/views/handlers/views_handler_field.inc). Notice: Undefined index: phase in views_handler_field->render_text() (line 1095 of /srv/www/julio/html/profiles/julio/modules/views/handlers/views_handler_field.inc).

(This happens when I got to the Manage Members menu, select a user, choose Modify OG user roles from the Choose Operation pulldown, hit execute, choose administrator member, hit Next, and then hit Confirm.)

Like I said, the change does actually go through, but I still get that error message, which hangs out, until I back out of the Admin Dashboard.
