[Juser] Trouble joining MUCs at conference.jabber.ru

For the past few months or so I've been experiencing problems with MUCs 
hosted on conference.jabber.ru. I've spoken to admins of jabber.ru, and 
it appears that jabber.org drops the server-to-server connection to 
jabber.ru. Details follow.

First, the symptoms. I have more than 10 MUCs in my roster, and my 
client auto-joins them on startup. But for most of those MUCs, 
I immediately receive the following error:

    <presence from='X at conference.jabber.ru/Me'
        This participant is kicked from the room because he sent an
        error presence: remote-server-not-found
      <x xmlns='http://jabber.org/protocol/muc#user'>
        <item affiliation='member' role='none'/>
        <status code='110'/>

And if I'm not kicked out of the MUC with the aforementioned error, last 
messages log and/or topic are often missing, and I often don't see 
myself in the users list of these MUCs. Rejoining the conferences (by 
hand) sometimes help, but there are a small set of MUCs where rejoining 
consistently *doesn't* help.

Here's how situation looks like from jabber.ru's standpoint: 
http://lpaste.net/858522898288082944 The payload is the topic of one of 
the conferences I join. As you can see, jabber.org terminates the 
connection right afterwards (line 50). My client never gets the topic.

I tried both mcabber 1.0.0 and Psi 0.14—the problems are the same 
regardless of the client.

I'm Minoru on jabber at conference.jabber.org, online usually from 12pm 
till 9pm UTC, and am ready to cooperate if any of the admins are willing 
to investigate. I'm also subscribed to the list and will provide any 
details you require.
