Deleting avatar / vcards problem
-Deleting avatar and publishing vcard does not delete avatar in account row tooltip.
-We still see our old avatar in the room we are if we don't ask manually. Because we send no sha in presence. But sometimes some groupchat servers delete the sha, so I'm not sure we can safely delete avatar if no sha.
-If someone on a room (at least, maybe a contact too) used to have an avatar and now have no vcard at all, like this {{{ <iq id='916' type='error' to='jim@jabber.fr/Gajim' from='psi@conference.jabber.ru/remko'> <vCard xmlns='vcard-temp'/> <error type='cancel'> <feature-not-implemented xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/> </error> </iq> }}} , we still see his old avatar in tooltip but nothing in gc-roster.
