Extra spaces added to classes name with Sublime Text 2

Question

I have a weird problem with Sublime Text 2.

When I write CSS classes, it add automatically a space who is associated to the class name and not interpret like a simple separator. This arrive after I put the bracket and press tab (shortcut for the autocompletion).

So when I write this class to my HTML, it didn't works because of the extra padding added (and I am looking for always for a long time, where the error came from, and it's only about this space added to the class name).

I create a jsfiddle and copy/paste little code from my sublime text 2 : http://jsfiddle.net/SB3KV/

<div class="myclass"></div>

.myclass {
    background: red;
    width: 100px;
    height: 100px;
}

I use several extensions : Emmet, GitGutter, LESS, Package Control, SFTP, Sass, Theme Phoenix and PyV8 (automatically add with SFTP)

Bad way

(I press the key tab)

(the result)

Good way

(the correct behavior I want)

So how, can I fix this problem who give so many trouble ?

Update 1

Ok, it's seems to be the weirdest problem I have ever seen.

I make some search, but nothing interesting.

I deleted all my custom user preferences, nothing change, I remove all my packages, nothing change. I delete the ST2 application, no improvements, I also installed ST3 and I have the same strange issue.

It's the most boring problem I have encountered.

NOTE

When I inspect the class name element copy/paste from ST2 on jsfiddle or even in stackoverflow, there is a non-breaking space. It's should be the problem, but I don't know at all, why it's adding this space after the class name.

Big Update 2

I think the problem didn't come from sublime text 2 only.

I tried to create a simple div on codepen http://codepen.io/anon/pen/wDrxn or jsfiddle http://jsfiddle.net/2SJUQ/ and it didn't work.

So, as you can see, there is a f*****k   added between the end of the class name and the bracket. I have tried on 3 differents Mac, and I have the problem, on all of them. At this point, I can't figure out why I have this problem. They are all of 3 on Mavericks, can the problem come from this?
