Thunderbird 3 Shows only English dictionary in Spell menu

This also affects me. I have the thunderbird-locale-en-gb and myspell-en-gb packages installed. Thunderbird shows the language pack correctly installed under 'Tools > Add-ons > Languages'. However, I am only able to select the United States English dictionary when composing email.

Current package versions (Lucid):
thunderbird: 3.0.4+nobinonly-0ubuntu1
thunderbird-locale-en-gb: 1:3.0-0ubuntu2
myspell-en-gb: 1:3.2.0-2ubuntu2

This problem is caused by Thunderbird not correctly linking the myspell dictionaries into '/usr/lib/thunderbird-3.0.4/dictionaries/'. I believe there are two possible solutions to this problem:

1) Link Thunderbird's dictionaries directory to the myspell dictionaries directory. This is the solution currently used by Firefox:
  '/usr/lib/thunderbird-3.0.4/dictionaries -> ../../share/myspell/dicts'
  c.f. '/usr/lib/firefox-3.6.3/dictionaries -> ../../share/myspell/dicts'.

2) Link the individual dictionaries at the thunderbird-locale level. This would probably entail making the locale package dependant on the appropriate myspell dictionary pack, e.g.:
  thunderbird-locale-en-gb:
    Depends: myspell-en-gb

  '/usr/lib/thunderbird-3.0.4/dictionaries/en-GB.dic -> ../../../share/myspell/dicts/en-GB.dic'
  '/usr/lib/thunderbird-3.0.4/dictionaries/en-GB.aff -> ../../../share/myspell/dicts/en-GB.aff'.

Tested the above suggestion and it worked, I would suggest making this link

I confirm that the solution works:

sudo ln -s /usr/share/myspell/dicts/ /usr/lib/thunderbird-3.0.4/dictionaries

then restart thunderbird and all dictionaries are now listed.

This bug was fixed in the package thunderbird - 3.0.4+nobinonly-0ubuntu4

  * Fix LP: #543060 - gnome integration should work even without -gnome-support.
    Move the gnome components to the main thunderbird package whilst using
    thunderbird-gnome-support to pull in the gnome dependencies:
    - update debian/rules
    - remove debian/thunderbird-gnome-support.postinst.in
    - remove debian/thunderbird-gnome-support.prerm.in
    - add replaces/breaks to thunderbird on previous versions of
      thunderbird-gnome-supportm to ensure the upgrade works
