Comment 23 for bug 817326

I just lost a document I have been working on for weeks, due to the Ubuntu overheating-problem, which caused a power-failure, and then due to this bug in LibreOffice, which cost me weeks of work.
I am depending on Libreoffice due to the special features I require, which make it easier to write in a rare language, and would otherwise be difficult to accomplish.
I hope this will have a solution soon, as I cannot risk loosing any more work.
There is only version 3.4.4 available in the repositories.
No fixes with updates?
I appreciate your help!
