Comment 4 for bug 157921

The issue is caused by myspell-en-au, myspell-en-gb and myspell-en-us, which create both the en_*.dic/aff files, and the en-* links (Note the difference between _ and -). I'm not a programmer and don't know how firefox works, but I suspect it's just scanning all files in the /usr/share/myspell/dicts directory which is why it ends up with two copies. The '-' version is the one firefox likes as it gives the proper name to it. Can the '_' version simply be renamed, or do applications use this version?

dictionary.lst appears to be an OpenOffice.org thing (installed by openoffice.org-common). I'm by no definition an expert in this area, but it seems like there needs to be an improvement of standards in the dictionary/languages area.
