I'm executing the following code

```
import selenium
from selenium import webdriver
driver = webdriver.Remote(command_executor="http://selenium.server.com:4444/wd/hub", desired_capabilities="webdriver.DesiredCapabilities.FIREFOX")
driver.implicitly_wait(60)
driver.get('http://www.google.com')

```

But it's causing an exception

> 
> 7610 [SocketListener0-1] INFO org.openqa.jetty.jetty.context./wd - WebDriver remote server: Fatal, unhandled exception: /session:java.lang.ClassCastException:java.lang.String cannot be cast to java.util.Map

I have written it as bug, but what to make sure from experts here that whether it's a bug or something I'm missing.
