Chrome Version       : 49.0.2623.110 (64-bit)
URLs (if applicable) : https://github.com/GoogleChrome/chrome-app-samples/issues/436

What steps will reproduce the problem?
1. Run the sample app and confirm that sign in works well.
2. Go to your language settings and change your language to Korean
3. Quit Chrome browser completely and open it again -- the browser should be in Korean now.
4. Run the sample app and encounter chrome.runtime.identity.getAuthToken: Authorization page could not be loaded error.

What is the expected result?
I should get the token in the callback without any exception in any locale

What happens instead?
You get an exception and token is undefined in the callback. This only happens in a specific locale.

Please provide any additional information below. Attach a screenshot if
possible.

Problem:
chrome.identity.getAuthToken() function throws {"message":"Authorization page could not be loaded."} error and returns undefined for token when a Chrome app runs in Korean locale.

I was having this problem with my Chrome app (quite puzzling because sign in doesn't work only in a certain locale) and I thought I did something wrong. I came here to look for the answer, and found out that the sample app is having the same problem. I tried the following things:

- Add the following domains to permissions in manifest.js
    "https://*.chromiumapp.org/*", "https://chromiumapp.org/",
    "https://*.apps.googleusercontent.com/", "https://apps.googleusercontent.com/",
    "https://apps.googleusercontent.com/", "https://*.chromiumapp.org/*/*",
    "*://*.google.com/*", "https://accounts.google.com/o/oauth2/v2/auth"
- Add key field in manifest.js so that App ID is the same for both production and development.
- Check that OAuth2 Client key has the right App ID.
- Use chrome.identity.launchWebAuthFlow in place of chrome.identity.getAuthToken
- Change the 'interactive': true option to false
- Call chrome.identity.getAuthToken({ 'interactive': true } twice
- Call chrome.identity.getAuthToken in the callback of chrome.identity.onSignInChanged

None of the above worked.
I am happy to invite you to see my code on GitHub if that helps.
