----------------------+--------------------
 I am using XEP-0198 with a prosody server and yaxim as client (yaxim in
 the nightly version that supports it) and pidgin as the second partner in
 the chat. For the case where the client (yaxim) loses connectivity and
 reconnects before the session timeout runs out, everything works great.
 For the case where the session timeout happens, there is the following
 problem.

 According to XEP-0198, "A server SHOULD treat unacknowledged stanzas in
 the same way that it would treat a stanza sent to an unavailable resource,
 by either returning an error to the sender or committing the stanza to
 offline storage." I.e. it is legal for the server to return an error. The
 implementation of XEP-0198 for prosody does this as described here
 http://code.google.com/p/prosody-modules/wiki/mod_smacks namely "If the
 client fails to reconnect before the timeout then it is marked offline as
 normal, and any stanzas in the queue are returned to the sender as a
 "recipient-unavailable" error."

 From what I understand and have seen, this error is a stanza that has the
 same message ID as the original message it relates to, no content and is
 of 'type="error"'.

 If pidgin as a sender receives such an error (because the intended
 recipient of the message lost network connectivity long enough to trigger
 the timeout on the server) it SHOULD (imo) inform the sending user of this
 error. It doesn't. IMO this is a bug.

 It is clear from the server debug logs that the error stanza is received
 by pidgin, pidgin just doesn't show anything to the user.
