Input groups bigger than input in Bootstrap 3 using Jumbotron container

I'm experimenting a strange behavior with Bootstrap 3 input groups. When I add an input-group-addon (text or icon) to a form inside a jumbotron, the input-group height is bigger than its input height.

Here you can find a JsFiddle and an screenshot with the problem:

<div class="jumbotron">
<h1>Jumbotron with form</h1>
<div class="input-group">
<input type="text" class="form-control" placeholder="Username">
<span class="input-group-addon">@</span>

Live example at http://jsfiddle.net/DTcHh/

How can I fix this problem? I'm looking for a Bootstrap solution but if that's not possible would be nice if you could help me to fix it with CSS rules.
