When adding a twitter account, sign-in page is in local language instead of the language I have selected in Ubuntu

When you add a twitter account, gwibber needs to authenticate with Twitter. The problem is that the twitter sign-in page appears in the language of the location you're at, rather than the language you have selected on your ubuntu installation.
The problem with this is when you happen to be in - or live in - a country who's default language selected by twitter you do not understand. In my case, my ubuntu is in English, but I'm in the Philippines. English and Tagalog are the official languages in the Philippines, but there are about 80 other languages. I'd say Twitter's choice of Tagalog as default is stupid - they should default to English, but that's another case. I'm sure I can manage to guess my way through the login screen (although I wouldn't understand what I'm giving gwibber permission to do), but I'm logging this because the principle is problematic. What if I was in Iran or China or Japan? I surely wouldn't understand *anything* on that login page.
What if I was in Switzerland? Which of the 4 official languages there would I be presented with?
We need to find a way to tell Twitter, and other services, which language we're actually using, regardless of which country we're in.

By the way, my version is 3.4.2, running on Ubuntu 12.04.1 LTS (Precise)
