Comment 15 for bug 1240058

In a discussion on IRC the other day, it was considered better to create a new accountsservice method to deal with this issue than to make SetLanguage behave differently depending on platform.

However, later on it struck me that this whole issue is due to the UI in language-selector, which - unlike all other UIs for setting the user language - sets a LANGUAGE priority list. After having given this some more thought, I think that a new method would be to overdo it. Instead I have uploaded a change that checks for the existence of the language-selector-gnome package. If it's not there, LANGUAGE is assigned only a single language code.
