We have had continuing issues with our OOo 2 documents freezing the Writer
completely when trying to open them. We then have to use ask Manager to close
the Program and the file is seemingly useless.

After looking at some of the previous filed issues I managed to unzip the file
and edit the content.xml directly. It turns out that something has been
happening with the auto bibliography table and it keeps on looping through and
filling the XML with _5f. I have to cut and replace the offending section in
order to recover the document. Here is an example of the XML that is produced:

<text:index-entry-span>.</text:index-entry-span><text:index-entry-bibliography
text:style-name="biblio_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f_5f

And the _5f's go on for thousands of lines of code!

I have attached an example document here.
