[Bug 995054] [NEW] thunderbird looses langpacks after upgrade

[urusha]

Public bug reported:

Hi.
After upgrading thunderbird to version 12.0.1+build1-0ubuntu0.10.04.1 on 10.04 I cannot see any system-wide langpack in the addons menu. The reason of it is that somehow (I think it's the order of package installation/configuring ) '/usr/lib/thunderbird/extensions' becomes a directory while upgrade  (it should be symlink to '/usr/lib/thunderbird-addons/etenstions' normally). So, all langpacks stays in '/usr/lib/thunderbird-addons/extensions', but thunderbird doesn't detect them. I don't see this problem on 12.04, I think it's because it already had /usr/lib/thunderbird folder before upgrade, but ubuntu 10.04 used /usr/lib/thunderbird-a.b directories for storing thunderbird package data earlier, so it has this problem.

A quick solution is:
mv /usr/lib/thunderbird/extensions/* /usr/lib/thunderbird-addons/extensions
rmdir  /usr/lib/thunderbird/extensions
ln -s /usr/lib/thunderbird-addons/extensions /usr/lib/thunderbird

This bug has already affected many machines in our office.

Thanks.
