Twitter suggestions returning 404?

Question

Running Twitter gem version 1.7.2, OSX Lion, Ruby 1.9.2.

In Rails console.. if you put:

client = Twitter::Client.new(:oauth_token => actual_token_here, :oauth_token_secret => actual_secret_here)
client.suggestions('entertainment')

It retrieves results from Twitter's API. But:

client = Twitter::Client.new
client.suggestions('entertainment')

Returns the same error:

Twitter::NotFound: GET https://api.twitter.com/1/users/suggestions/entertainment.json: 404: Can't find that category

https://dev.twitter.com/docs/api/1/get/users/suggestions/%3Aslug suggests that you don't need to be authenticated to make this API call.

So shouldn't it work without the tokens as well? The strange this is , I've asked someone else to do this on their dev machine and it works fine. I don't know where to proceed from here. How can I track where the problem is coming from?

This is the full trace:

Twitter::NotFound: GET https://api.twitter.com/1/users/suggestions/entertainment.json: 404: Can't find that category

Errr. for some reason, I needed to specify the lang param. For example:

client.suggestions("entertainment", :lang => "en")

Works now!
