Steps:
1. Download LibreOffice 3.3.0.4 from here: http://downloadarchive.documentfoundation.org/libreoffice/old/3.3.0.4/

2. Open this query: 
https://bugs.freedesktop.org/buglist.cgi?list_id=430801&query_format=advanced&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&version=PreBibisect&product=LibreOffice

3. Test to see if the bug reported was around with 3.3.0.4

4. If bug was around with 3.3.0.4 set version to "Inherited from OOo"

5. If bug was not around with 3.3.0.4 (and the bug is not about a new feature added by LibreOffice) do the following:

a. Leave a comment saying that the bug is not present in 3.3.0.4 & include information about your computer (Operating System)

b. Add "regression" to keyword - before adding regression be sure that the bug isn't about a new feature (ie. someone made a new feature that had the bug from the beginning, this is not a regression). A regression literally means at one point the bug was not present and everything worked fine, and then it was broken :)
