It failed a unit test in subscription manager. 

```
   def test_main_proxy_url(self):
        proxy_host = "example.com"
        proxy_port = "3128"
        proxy_url = "%s:%s" % (proxy_host, proxy_port)
        self.cc.main(["--proxy", proxy_url])
        self.assertEquals(proxy_url, self.cc.options.proxy_url)
        self.assertEquals(type(proxy_url), type(self.cc.options.proxy_url))
        self.assertEquals(proxy_host, self.cc.proxy_hostname)
        self.assertEquals(int(proxy_port), self.cc.proxy_port)
```

That caused me to go back and change everything back to ints. Which was done in commit c31c07af
