demm I figured something had changed, thanks for clearing that up.
Yes, I have both hunspell and aspell and both 'en' and 'sv' packages installed for both (sv packages are built from AUR). Adding the hunspell/aspell-sv packages to repo would be nice I also tried adding Swedish dic from mozilla itself as an addon, but nothing.
Most topics I found about this was missing dics, but that's not the issue here.
[EDIT] I just looked in my system, and I still have /usr/share/locale and lots of folders in there. From the link you posted, it should have been deleted?
