[jdev] if anyone is having problems with slow propogation for <x xmlns="MY_NAMESPACE" messages...

Just discovered something interesting with jabber1.4.3 and muc 0.6.0.

I've been having a problem with my jabber install where it's only
allowing messages at a rate of about 1 every 2 seconds and dropping
messages in between. I thought the problem was karma or maybe something
in the config. What I finally figured out is that jabber just doesn't
like <message> messages that don't have a non-empty <body> element. 

What I had been sending were game-event messages that looked like this:

<message>
	<x xmlns="mtvn/games">
	// game event payload here
  	</x>
</message>

...no matter what I tried, these message would start to propogate very
slowly after I had sent the first few.

I finally tried a test where I sent regular messages with a <body> and
those propogated normally. I experimented a bit and now I'm doing this:

<message>	
	// this dummy body element seems to make jabber happy
	// it doesn't work if you just send <body/>
	<body>1</body> 
	<x xmlns="mtvn/games">
	// game event payload here
  	</x>
</message>

...and propogation speed is back to normal.

I didn't look into jabber's internals at all to figure out why this
might be so. Just thought I'd put it out there in case anyone comes
across a similar problem.
