There exists no documents produced by LibreOffice, where text on OLE
objects has worked, because import expects the paragraphs inside the
draw:object element, but LO has written them outside. The patch
changes LO to write the paragraphs inside the draw:object element.
The patch does not enable LibreOffice to read the paragraphs in
old documents. But versions at least since 5.1 will be able to read
text on OLE objects from documents which were produced by versions
with applied patch.
