collapsible fieldset not working

I am not sure I can post here due to the fact this bug is about bootstrap 3.0, but if I can't post here where shoud I post for a Drupal/stable Boostrap bug?
Here is the bug:
If I create collapsible fieldset using field_group, they will not work under a bootstrap theme. If I change the theme for this page, they will work.
Here is the generate html for this fieldset:

		<fieldset
			class="collapsible collapsed panel panel-default form-wrapper collapse-processed">
			<legend class="panel-heading">
				<a href="#" class="panel-title fieldset-legend"
					data-toggle="collapse"><a class="fieldset-title" href="#"><span
						class="fieldset-legend-prefix element-invisible">Afficher</span>
						Ma société </a><span class="summary"></span></a>
			</legend>
			<div id="" class="panel-collapse collapse fade">
				<div class="panel-body">
					<div
						class="field-type-text field-name-field-company-name field-widget-text-textfield form-wrapper form-group"
