ODT file created in OOo 2.0.4.  It contains a single pagraph with a double border.  When this file is opened in LibreOffice 3.4, the paragraph border is lost.

Problem description: 

In earlier versions and in OOo, you could create double borders for paragraphs where the two lines of the border were not the same width.  In content.xml, it would be set as something like this:

border-line-width="0.0008in 0.0346in 0.0138in"  

When a file with this kind of formatting is opened in LibreOffice 3.4, the border is not displayed, and if the file is saved again, the border data is lost.

It is not just that the border is not displayed properly.  It is that the border data is completely lost when the file is saved again.

Steps to reproduce:
1. Use an earlier version of OOo or LibreOffice to create a document with a paragraph with a double border for which the two border lines are different in width.  (See attachment.)
2. Open that document in LibreOffice 3.4 and save the document under a new file name.
3. Looking at content.xml or opening the new document in an older version shows that the border has been lost.


A simpler way to reproduce the problem:
1. Open a new document in LibreOffice 3.4.
2. Type "***" (without the quotes) and press enter.  The asterisks will be auto-replaced with a double horizontal line (actually an empty paragraph with a double bottom border).  For this double border, the lines are of different width.
3.  Save the document and close it.
4.  Open the document you saved, and the horizontal lines will be gone.

Current behavior:  Paragraphs lose border when the document is opened.

Expected behavior:  Borders are preserved.
