For some reason I have an extra unneeded language installed on my system (more precisely, `$LANGUAGE` variable is `ru:en_CA:en` where supposed to be `ru:en`, and also apt tries to load addresses like `http://ppa.launchpad.net precise/main Translation-en_CA`).

How can I remove the unneeded `en_CA` language?

* `language-selector` doesn't have an option to remove a language
* `localepurge` doesn't help
