Openfire server pep based avatars , Android client

Question

I have setup openfire server and my android clients works well with it except that I am unable to publish avatars , the problem is that the server simply ignores the publish avatar iq packet , no errors , nothing in the log files. I am using standard XMPP pep avatar stanza , please hep

Thankyou for your replies everyone, I found that the issue is with openfire server 3.10 which does not parse the standard XEP 0084 stanza well, infact I found the logs and server was crashing so i modified the IQ as , for example this should be the standard IQ for publishing avatar

<iq type='set' from='[email protected]/chamber' id='publish1'>
  <pubsub xmlns='http://jabber.org/protocol/pubsub'>
    <publish node='urn:xmpp:avatar:data'>
      <item id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'>
        <data xmlns='urn:xmpp:avatar:data'>
          qANQR1DBwU4DX7jmYZnncm...
        </data>
      </item>
    </publish>
  </pubsub>
</iq>

but as you can see there is no "to" address in the standard IQ , openfire server would create the pubsub node in DB and crash and would not reply with result asking the user to now publish metadata ,so what i had to do is send this packet and then the standard metadata packet , but then send meta data packet again with a "to" address which would be replied by the server as result that the metadata notification succeded as standard meta data to be sent to server for the first time ,

<iq type='set' from='[email protected]/chamber' id='publish2'>
      <pubsub xmlns='http://jabber.org/protocol/pubsub'>
        <publish node='urn:xmpp:avatar:metadata'>
          <item id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'>
            <metadata xmlns='urn:xmpp:avatar:metadata'>
              <info bytes='12345'
                    id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'
                    height='64'
                    type='image/png'
                    width='64'/>
            </metadata>
          </item>
        </publish>
      </pubsub>
    </iq>

and then again like this with addition of "to" address

<iq type='set' from='[email protected]/chamber' to="mydomain.com" id='publish2'>
  <pubsub xmlns='http://jabber.org/protocol/pubsub'>
    <publish node='urn:xmpp:avatar:metadata'>
      <item id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'>
        <metadata xmlns='urn:xmpp:avatar:metadata'>
          <info bytes='12345'
                id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'
                height='64'
                type='image/png'
                width='64'/>
        </metadata>
      </item>
    </publish>
  </pubsub>
</iq>

in the above way avatar publishing is working and Im successfully issuing a notification to other users also

and here is the server crash log incase
