just a quick update: I implemented a quick workaround for now, which
has hunspell/myspell hardcoded. it seems to be working for now:

def spell(self, aWord, aLocale, aProperties ):

    if not self.myspell:
        self.myspell = self.service_manager.createInstance
("org.openoffice.lingu.MySpellSpellChecker")

    if self.myspell:
        return self.myspell.spell (aWord, aLocale, aProperties)

    return None
