created new patch for Joomla issue tracker item http://joomlacode.org/gf/project/joomla/tracker/?action=TrackerItemEdit&tracker_item_id=29362
old patch was too old and cannot be applied anymore. 

New patch introduces .visible-bootstrap. Was not used in Joomla before so styling broke a bit.
Known issue in Bootstrap and solution suggested in Bootstrap issue tracker item 5206
