I have finally been able to have Libreoffice 4.4 (via ppa) and Mendeley 13.3 working. The same as the user shaneonabike comments on https://forums.zotero.org/discussion/46297/ , by completely uninstalling the plugin, then updating and then reinstalling the plugin, the problem seems to be sorted when you open Libreoffice. I hope it might help others!
