Comment 112 for bug 66015

It seems that Thunderbird and Firefox now correctly recognize ln_RE file names for the dictionaries (in Lucid at least). The problem is that they also recognize ln-RE names and this causes duplication of entries in the list of supported dictionaries.
I fixed this by removing all files with hyphen by 'sudo rm ??-*' from /usr/share/myspell/dicts/ and /usr/share/hunspell/ (as all dictionaries in myspell folder have links to hunspell). You can backup these files instead of removing them if you wish to play safe, but files ln_RE.* and ln-RE.* are duplicates.
I checked OpenOffice and both TB and FF - spell checking works normally everywhere and Mozilla products now have only single entry for each language. (I'm using Ubuntu Lucid, FF 3.6.13, TB 3.1.7)
