LibreOffice was updated to version 5.1.5.2, bringing enhancements and bug fixes.

- CVE-2016-4324: Parsing the Rich Text Format character style index was insufficiently
checked for validity. Documents could be constructed which dereference an iterator to
the first entry of an empty STL container. (bsc#987553)
- Don't use "nullable" for introspection, as it isn't available on SLE 12's version
of gobject-introspection. This prevents a segmentation fault in gnome-documents.
(bsc#1000102)
