If the entry currently has any subscription state, the server will send the corresponding unsubscribing presence stanzas. `timeout` is the maximum time in seconds to wait for a reply from the server. This may raise arbitrary :class:`.errors.XMPPError` exceptions if the server replies with an error and also any kind of connection error if the connection gets fatally terminated while waiting for a response.
