Dictionary error with Facebook SDK

I am trying to get the user's locale but I am having trouble doing so. My App has been approved by facebook to use the user_location permission.

In my script I request the permission with: permissions.Add("user_location");

then

FB.API("/me?fields=location", HttpMethod.GET, DisplayLocation);

void DisplayLocation(IResult result)
{
if (result.ResultDictionary.ContainsKey("locale"))
{
FacebookLocation = result.ResultDictionary["locale"];
PlayerPrefs.SetString("location", FacebookLocation.ToString());

}
}

However, I keep getting the error that locale isn't in the dictionary. I've also tried replacing locale with hometown but get the same error. I am using the same code to get gender, name etc. and that all works fine.

Here is the full error:

KeyNotFoundException: The given key was not present in the dictionary.
