Events created with KOrganizer duplicate the identity name inside <>, which creates confusion for downstream applications that don't properly parse the CN and turn it into an email address: "ORGANIZER;CN=Anthony Messina <Anthony Messina>".  Additionally, the invites are sent From: "Anthony Messina <Anthony Messina>" <amessina@example.com>"

While it may be technically OK do do this, duplicating the identity name doesn't seem to serve a purpose. Please don't duplicate the identity name in <> brackets in the From: or the CN.
