Exception in AsynchElementStream: invalid end tag

[GoogleCodeExporter]

In an effort to determine which of my available contacts supports what, I'm
using a DiscoManager to request disco#info the first time a <presence>
element for a particular JID arrives.  It looks like there might be some
crosstalk with so much data coming in at the same time.

I'm emailing a full dump of the sent and received data, and the exception
stack trace, to hildjj at gmail.com - emailing rather attaching because it
contains JIDs and so forth.

============ Offending code follows ============

/// <summary>
/// Requests discovery of features for the specified JID
/// </summary>
private void DiscoverFeatures(JID jid)
{
    discoManager.BeginGetFeatures(jid, "", discoManager_GetFeatures, null);
}

...

/// <summary>
/// Processes a presence update event
/// </summary>
private void jabberSession_OnPresence(object sender,
jabber.protocol.client.Presence pres)
{
    if (!HaveFeaturesBeenDiscovered(pres.From))
    {
        DiscoverFeatures(pres.From);
    }
}

============ Code ends ============

If you look at the dump file sent around line 200, there appears to be very
strange things going on with the Blackberry client on the roster - it
redeclares all the usual xml namespaces in its initial presence
notification.  Maybe that's what's causing the choke?
