XMPP errors after sending messages are ignored

Miranda Version                  : v0.10.20.0
Unicode Build                    : Yes
Plugin Version # (if applicable) : jabber.dll 0.10.20, History++ 1.5.1.4

Right now my XMPP server is not working, it's returning errors on every message 
and iq.

Me:
<message type="chat" to="<>" id="mir_12">
<body>j</body>
</message>

Server:
<message type="error" to="<>/Home" from="<>" xml:lang="en" id="mir_12">
<error code="500" type="wait">
<internal-server-error xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" />
</error>
</message>

However, Miranda ignores the error. There's no indication that the message 
hasn't been delivered. 

I've seen non-delivery indication when XEP-0184 (Message Delivery Receipt) 
timed out. So in general message delivery error handling seems to be at least 
partially supported.

I'm not sure which bug it is - Miranda core or History++, so please excuse me 
if I'm posting the bug to the wrong tracker.
