OpenOffice crashes after fail to recover documents

When launching openoffice, it starts to recover some files which previously did not save properly. After it recovers, it just display a message saying it needed to close due to some unexpected error. After retrying to start a few more times, the result is still the same. Reset the profile by using the below instructions :

mv ~/.openoffice.org openoffice.org.backup
mv ~/.openoffice.org2(or 3) openoffice.org.backup

Try re-launching openoffice again

Voilla !!!
