Is that translation on pootled has been integrated into 3.3 Rc4
Let's make it clear, the following have been integrated:
* translation from OOo 3.3 source code
* extra LibreOffice translation from TDF Pootle (lo-build-vi.po in your case)
If you have corrections in OOo Pootle that have not been integrated to
OOo 3.3, then please let me know. I don't do automatic updates from
OOo Pootle for any language.
Best regards,
Andras
