Cheeaun MooEditable → 0.5

I use the very last version of mooeditable which seems to work well except this very annoying bug I have :
The last sentence I write is always repeated twice if I write more than one line.

Let me show you the code I use :

window.addEvent('domready', function(){

var myMooEditable = new MooEditable('myEditor', {
    handleSubmit: true,
    paragraphise: false,
    actions: 'bold italic underline strikethrough | insertunorderedlist | undo redo | createlink unlink | toggleview'
});

$('myForm').addEvent('submit', function(evt){
    console.log( myMooEditable.getContent() );
    console.log( $('myEditor').get('value') );
    evt.stop();
    doStuffsThenSubmit();
});

});

If I fill the editor with the sentence
Hello world

My console will output
Hello world

<p>Hello world</p>

But if I fill it with
Hello World

How are you ?

My console output
Hello world<br />How are you ?

<p>Hello world<br>How are you ?</p>How are you ?

I'm a little bit disapoited. Did I miss something ? I can't believe I'm the only guy who found this bug, have I done something wrong in my mooeditable instanciation ?
