I just went back with poedit and updated all the translation files to match the newest source and there are quite a few new strings which need to be translated. Please go to
https://github.com/TheBlueMatt/bitcoin/tree/translations/locale, click on the language you wish to translate, LC_MESSAGES, and bitcoin.po. Download the raw file and search for msgstr "" within, and update the translation of whatever is in the msgid above. When you have an updated bitcoin.po, please post it here and Ill make sure it gets merged upstream into the next bitcoin release. If you want to add a new translation, feel free to download any bitcoin.po and update all of the msgstr's with new ones, and post it here, making sure to specify what language you are translating.
EDIT: Got a spanish one, still need a ton more though...thanks.
