I would first check the versions on your libs.
If you are using a version before this pull request you may be pointing to assets that don't exist. The Bootstrap 3.0.0-wip branch has abstracted glyphicons out to this repo.
I would also preceed the URL asset paths with a /
to invoke from base URL.
<link rel="stylesheet" href="/bootstrap/css/bootstrap.css">
<link rel="stylesheet" href="/bootstrap/css/bootstrap-glyphicons.css">
On the offical glyphicons lander, an example uses <span></span>
rather than <i></i>
<span class="glyphicon glyphicon-ok"></span>
It is possible they changed that convention.
EDIT
In the source you will see the absolute paths of the assets. Double check that your fonts
directory is on the same level as the css
directory.
src:url('../fonts/glyphiconshalflings-regular.eot');
