启用 Project Babel 2 内置的 Twitter 客户端没有成功，请教几个问题。

1. http://dev.twitter.com/apps/new 页面的 Callback URL 填写的是 http://aaaaaaa.appspot.com/settings 不知道对不对。

2.申请到 Twitter 网站上的 OAuth Consumer Key 和 Secret 了。

也写入 config.py 了，不知道是不是这样：

if os.environ['SERVER_SOFTWARE'] == 'Development/1.0':
twitter_consumer_key = 'aaaaaaaMUWXfQtdpw'
twitter_consumer_secret = 'aaaaaaaIRMuAzk5oBplLndTzszbcJPLVZs'
else:
twitter_consumer_key = 'aaaaaaaIJMUWXfQtdpw'
twitter_consumer_secret = 'aaaaaaaYZuIRMuAzk5oBplLndTzszbcJPLVZs'

3.在绑定账户时，前几天是点击后，twitter 的界面出现，工作一会后，返回原地，但小鸟没有出现。

刚才在 config.py 胡乱改了一下，也恢复原样了，但总出现下面的错误，不知道怎么回事。
