After upgrading to Mavericks on my MacBook Air I decided to once again try the upgrade from 3.4.1 to 4.0.1. I tried this upgrade with Mountain Lion and found it to be problematic with my 8000 page document written in Devanagari. I downgraded back to 3.4.1 and eventually the document stabilized. So after upgrading to Mavericks I decided to once again try 4.0.1. 

This time document seems to be loading and working correctly. However every time upon opening the document in OpenOffice I get an error message and this error may also arrive for this very same 8000 page document when opening other documents. Yet the recovery is fake, nothing happens and the selected document opens. 

Thing is I know it did not crash last time. I know it is not needing recovery. Yet if it did need recovery it would take up to minutes to recover but here it needs only a fraction of a second and the "recovery" is over and the document opens as if nothing had happened (needing recovery.) 

One more thing to mention is that it creates an invisible icon as an alias for this 8000 pager on the desktop. I have never seen this before - a bit spooky, no? I will ask about this as a separated issue.

Otherwise all seems to be well. The document, as so far I can tell, is running better than ever and loads more quickly.
