`cei:abstracts` displays an unexpected "x" at the end.

e.g. in http://www.monasterium.net/mom/DE-GAUnivGoet/AppDipl/App_dipl_2/charter or http://www.monasterium.net/mom/DE-GAUnivGoet/AppDiplBrondolo/App_dipl_Brondolo_1/charter the abstract area of the charter display shows an "x" which which does not have any meaning. As it isn't part of the XML source, it probably is introduced by code.
