ubuntu tweak crashes on start up with Error: unsupported locale setting

You should first install the language pack in "Language Support".

I had som problems with locales(something with LC_ALL), so I reinstaled ubuntu, then I have installed localization. Now Ubuntu tweak works fine. But I think that it should work no matter what language I use because english is installed by default and I think it shoul use english instead of my local language.

I installed the language pack and the latest version of Tweak but the application still crashes. This is the message:

Error: unsupported locale setting

The latest version was still 0.5.4

i install the language pack in "Language Support". the bug is fix. Thx
