 1. A new "subscribe" presence comes in.
  1.
 [http://hg.pidgin.im/pidgin/main/file/f3069c38804b/libpurple/protocols/jabber/presence.c#l959
 This line] allocates a new {{{struct _jabber_add_permit}}}.
  1. {{{purple_account_request_authorization}}} is called.
  1. If a plugin returns {{{PURPLE_ACCOUNT_RESPONSE_IGNORE}}} for the
 request, or the UI ops directly call {{{purple_account_request_close}}},
 neither of the callbacks {{{authorize_add_cb}}}/{{{deny_add_cb}}} will be
 called.
  1. The {{{struct _jabber_add_permit}}} will now never be freed.
