The currently stable myspell-nl-20060316 no longer works with my stable openoffice-3.1.1 and hunspell-1.2.8. The dictionary itself is recognized and can be selected, but all words are not recognized and thus indentified as mis-spelled. Upgrading to myspell-nl-20070607 fixes this issue for me. I'm not cc'ing arches at this time since this may be a broader issue that might require other dicts to be stabled also. I've only tested myspell-nl.
