XEP-0045 says:

   The subject is changed by sending a message of type "groupchat" to the
   <room at service>, containing no body but a <subject/> that specifies the
   new subject: ...

I agree so far :-)

But Overloading the meaning of tags like this gives me the creeps...
It's certainly not a clean solution, in my opinion at least.
Maybe the subject element that means the room subject and the subject
element that means the conversation element should have different names
or at least a different namespace.

When looking at it: the <subject> child of a <message> tag is clearly
the 'message subject' and not the "topic" of a room or anything else.
But I guess it's too late now to change such things :-/

It could've clearly been something like this:

      from='wiccarocks at shakespeare.lit/laptop'
      to='darkcave at macbeth.shakespeare.lit'
      <query xmlns='http://jabber.org/protocol/muc#topic>This is a great subject for a room!</query>

And then the muc does send the same to it's clients...

Aww... whatever, ignore my rants :-)
