Subject: Error handler not being called

With the receive-XML error handler I can tell I'm getting the following:

<error xmlns="urn:ietf:params:xml:ns:xmpp-streams">
<not-authorized xmlns="urn:ietf:params:xml:ns:xmpp-streams" />
<text xmlns="urn:ietf:params:xml:ns:xmpp-streams" xml:lang="en-US">Stream Not Authenticated</text>
</error>

However, none of the other callbacks is being called. I would've expected the generic on error or stream error callbacks to be called.

(Why the stream is not authenticating in this case is a separate issue...)

this should raise an OnStreamError. When you post the complete Xml I can check again.

Here's an example from my debug output (mix of sent and received xml, with my event handlers indicated by []). I produce this by sending a message immediately after calling connect without waiting for the SendPresenceHandler, which I generally take to mean "Ready for messaging":

[SendXmlHandler event]
<message to="jeffkotula@mrp.vrad.com/con" xmlns="jabber:client">
<body>howdy</body>
</message>

[SendXmlHandler event]
<stream:stream xmlns:stream="http://etherx.jabber.org/streams" xmlns="jabber:client" to="mrp.vrad.com" version="1.0" >

[ReceiveXmlHandler event]
<stream:stream xmlns:stream="http://etherx.jabber.org/streams" from="mrp.vrad.com" xml:lang="en-us" id="2833749a-9eac-49fb-b3c3-4e88f6eb30fa" xmlns="jabber:client" version="1.0" >

[ReceiveXmlHandler event]
<stream:features xmlns:stream="http://etherx.jabber.org/streams">
<auth xmlns="http://jabber.org/features/iq-auth" />
<mechanisms xmlns="urn:ietf:params:xml:ns:xmpp-sasl">
<mechanism>PLAIN</mechanism>
</mechanisms>
</stream:features>

[StreamFeaturesHandler event]
[SendXmlHandler event]
<auth mechanism="PLAIN" xmlns="urn:ietf:params:xml:ns:xmpp-sasl">XXX</auth>

[ReceiveXmlHandler event]
<error xmlns="urn:ietf:params:xml:ns:xmpp-streams">
<not-authorized xmlns="urn:ietf:params:xml:ns:xmpp-streams" />
<text xmlns="urn:ietf:params:xml:ns:xmpp-streams" xml:lang="en-US">Stream Not Authenticated</text>
</error>

[ReceiveXmlHandler event]
</stream:stream>

[SendXmlHandler event]
</stream:stream>

[CloseHandler event]
[ErrorHandler event]

your test makes not much sense, because it sends the message before the xml stream got opened.

I have no problems to cause the OnStreamError event when I get the following xml:

<stream:error xmlns:stream="http://etherx.jabber.org/streams">
  <invalid-namespace xmlns="urn:ietf:params:xml:ns:xmpp-streams" />
</stream:error>

in your debug you don't have the stream prefix on the error element which is weird.
Which server software are you testing against?

I can investigate this problem further in detail when you want.
I need a full socket trace (eg. Wireshark) of a session then. When you run a socket trace you should connect with StartTls set to false.
